How to Convert PST to GMT time in php? - php

I would like convert PST to GMT.
Ex:
PST : 22:00 need to convert in to GMT. I have to consider about DAY LIGHT SAVING TIME month also.
How can i do that?

Use PHP's built-in DateTime class...
Use DateTime objects which have this functionality built in:
$date = new DateTime('2013-08-06 15:00:00', new DateTimeZone('America/Los_Angeles'));
echo "The time in Los Angeles is " . $date->format('Y-m-d H:i:s') . "<br>";
$date->setTimezone(new DateTimeZone('Europe/London'));
echo "The time in London is " . $date->format('Y-m-d H:i:s') . "<br>";
(Example Code) (Full Documentation)

I have to do similar for one my work and here it is how approached this:
//date time in PST
$t = 'Tue Feb 04 23:02:09 PST 2014';
$dateTime = DateTime::createFromFormat("D M d H:i:s \P\S\T Y", $t, (new DateTimeZone('America/Los_Angeles')));
var_dump($dateTime); // date time in PST format
$dateTime->setTimezone(new DateTimeZone('UTC'));
var_dump($dateTime); // date time in GMT format

How to convert GMT time to IST?

Here I am getting GMT Time as follow.
1520489880
Now I am getting This as
$myfinaldate = gmdate("d M H:i", $strtoDate);
So it will returns me GMT time. Now i want to convet it to IST(indian standard time).
where I stuck when I try
//Set timezone to india
date_default_timezone_set('Asia/Kolkata');
echo date('Y-m-d H:i:s');
But this returns me current time not the time that I get in strtotime
You need to pass the timestamp:
date_default_timezone_set('Asia/Kolkata');
echo date('d M H:i', $strToDate); // where $strToDate is 1520489880
Would produce the following value:
08 Mar 11:48
You can convert GMT time to IST time using following ways :
1.
echo date('Y-m-d H:i:s',strtotime('+330 minutes', 0));
2.
date_default_timezone_set('Asia/Kolkata');
echo date('Y-m-d H:i:s');
Changing default timezone is not such a good idea. Use DateTime class, any you don't need to worry about default timezone anymore...
$dt = new DateTime("#$strToDate");
$dt->setTimezone(new DateTimezone('Asia/Kolkata'));
echo $dt->format('Y-m-d H:i:s');

Converting date (with milliseconds) into timestamp

I have date format like '25 May 2016 10:45:53:567'.
I want to convert into the time stamp.
strtotime function returns empty.
$date = '25 May 2016 10:45:53:567';
echo strtotime($date);
// returns empty
When I removed the milliseconds, it's working.
$date = '25 May 2016 10:45:53';
echo strtotime($date);
// returns 1464153353
Please sort out my issue. Thanks in advance.
Use DateTime:
$date = DateTime::createFromFormat('d M Y H:i:s:u', '25 May 2016 10:45:53:000');
echo $date->getTimestamp();
// 1464165953
// With microseconds
echo $date->getTimestamp().'.'.$date->format('u');
// 1464165953.000000
Split string:
$date = '25 May 2016 10:45:53:001';
preg_match('/^(.+):(\d+)$/i', $date, $matches);
echo 'timestamp: ' . strtotime($matches[1]) . PHP_EOL;
echo 'milliseconds: ' . $matches[2] . PHP_EOL;
// timestamp: 1464162353
// milliseconds: 001
Use Datetime instead of date and strtotime.
//using date and strtotime
$date = '25 May 2016 10:45:53:000';
echo "Using date and strtotime: ".date("Y-m-d H:i:s.u", strtotime($date));
echo "\n";\
//using DateTime
$date = new DateTime();
$date->createFromFormat('d M Y H:i:s.u', '25 May 2016 10:45:53:000');
echo "Using DateTime: ".$date->format("Y-m-d H:i:s.u");
// since you want timestamp
echo $date->getTimestamp();
// Output
// Using date and strtotime: 1969-12-31 16:00:00.000000
// Using DateTime: 2016-05-28 03:25:22.000000

Which PHP function can return the current date/time?
The time would go by your server time. An easy workaround for this is to manually set the timezone by using date_default_timezone_set before the date() or time() functions are called to.
I'm in Melbourne, Australia so I have something like this:
date_default_timezone_set('Australia/Melbourne');
Or another example is LA - US:
date_default_timezone_set('America/Los_Angeles');
You can also see what timezone the server is currently in via:
date_default_timezone_get();
So something like:
$timezone = date_default_timezone_get();
echo "The current server timezone is: " . $timezone;
So the short answer for your question would be:
// Change the line below to your timezone!
date_default_timezone_set('Australia/Melbourne');
$date = date('m/d/Y h:i:s a', time());
Then all the times would be to the timezone you just set :)
// Simply:
$date = date('Y-m-d H:i:s');
// Or:
$date = date('Y/m/d H:i:s');
// This would return the date in the following formats respectively:
$date = '2012-03-06 17:33:07';
// Or
$date = '2012/03/06 17:33:07';
/**
* This time is based on the default server time zone.
* If you want the date in a different time zone,
* say if you come from Nairobi, Kenya like I do, you can set
* the time zone to Nairobi as shown below.
*/
date_default_timezone_set('Africa/Nairobi');
// Then call the date functions
$date = date('Y-m-d H:i:s');
// Or
$date = date('Y/m/d H:i:s');
// date_default_timezone_set() function is however
// supported by PHP version 5.1.0 or above.
For a time-zone reference, see List of Supported Timezones.
Since PHP 5.2.0 you can use the DateTime() class:
use \Datetime;
$now = new DateTime();
echo $now->format('Y-m-d H:i:s'); // MySQL datetime format
echo $now->getTimestamp(); // Unix Timestamp -- Since PHP 5.3
And to specify the timezone:
$now = new DateTime(null, new DateTimeZone('America/New_York'));
$now->setTimezone(new DateTimeZone('Europe/London')); // Another way
echo $now->getTimezone();
Reference: Here's a link
This can be more reliable than simply adding or subtracting the number of seconds in a day or a month to a timestamp because of daylight saving time.
The PHP code
// Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the
// Mountain Standard Time (MST) Time Zone
$today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm
$today = date("m.d.y"); // 03.10.01
$today = date("j, n, Y"); // 10, 3, 2001
$today = date("Ymd"); // 20010310
$today = date('h-i-s, j-m-y, it is w Day'); // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // it is the 10th day.
$today = date("D M j G:i:s T Y"); // Sat Mar 10 17:16:18 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:18 m is month
$today = date("H:i:s"); // 17:16:18
$today = date("Y-m-d H:i:s"); // 2001-03-10 17:16:18 (the MySQL DATETIME format)
PHP's time() returns a current Unix timestamp. With this, you can use the date() function to format it to your needs.
$date = date('Format String', time());
As Paolo mentioned in the comments, the second argument is redundant. The following snippet is equivalent to the one above:
$date = date('Format String');
You can either use the $_SERVER['REQUEST_TIME'] variable (available since PHP 5.1.0) or the time() function to get the current Unix timestamp.
You can use both the $_SERVER['REQUEST_TIME'] variable or the time() function. Both of these return a Unix timestamp.
Most of the time these two solutions will yield the exact same Unix Timestamp. The difference between these is that $_SERVER['REQUEST_TIME'] returns the time stamp of the most recent server request and time() returns the current time. This may create minor differences in accuracy depending on your application, but for most cases both of these solutions should suffice.
Based on your example code above, you are going to want to format this information once you obtain the Unix Timestamp. Unformatted Unix time looks like: 1232659628
So in order to get something that will work, you can use the date() function to format it.
A good reference for ways to use the date() function is located in the PHP Manual.
As an example, the following code returns a date that looks like this: 01/22/2009 04:35:00 pm :
echo date("m/d/Y h:i:s a", time());
PHP's date function can do this job.
date()
Description:
string date(string $format [, int $timestamp = time()])
Returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given.
Examples:
$today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm
$today = date("m.d.y"); // 03.10.01
$today = date("j, n, Y"); // 10, 3, 2001
$today = date("Ymd"); // 20010310
$today = date('h-i-s, j-m-y, it is w Day'); // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // it is the 10th day.
$today = date("D M j G:i:s T Y"); // Sat Mar 10 17:16:18 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:18 m is month
$today = date("H:i:s"); // 17:16:18
$today = date("Y-m-d H:i:s"); // 2001-03-10 17:16:18 (the MySQL DATETIME format)
For the new PHP programmer might confuse why there are lot of method for to get current date and time and which one to use in their project.
1. date method (PHP 4, PHP 5, PHP 7)
This is the very common and very easiest way to get the date and time in php.
// set the default timezone to use. Available since PHP 5.1
date_default_timezone_set('UTC');
// Prints something like: Monday
echo date("l");
// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A');
// Prints: July 1, 2000 is on a Saturday
echo "July 1, 2000 is on a " . date("l", mktime(0, 0, 0, 7, 1, 2000));
/* use the constants in the format parameter */
// prints something like: Wed, 25 Sep 2013 15:28:57 -0700
echo date(DATE_RFC2822);
// prints something like: 2000-07-01T00:00:00+00:00
echo date(DATE_ATOM, mktime(0, 0, 0, 7, 1, 2000));

2. DateTime class (PHP 5 >= 5.2.0, PHP 7)
when you want to use PHP with OOP, this is the best way to get date and time.
<?php
// Specified date/time in your computer's time zone.
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:sP') . "\n";
// Specified date/time in the specified time zone.
$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";
// Current date/time in your computer's time zone.
$date = new DateTime();
echo $date->format('Y-m-d H:i:sP') . "\n";
// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";
// Using a UNIX timestamp. Notice the result is in the UTC time zone.
$date = new DateTime('#946684800');
echo $date->format('Y-m-d H:i:sP') . "\n";
// Non-existent values roll over.
$date = new DateTime('2000-02-30');
echo $date->format('Y-m-d H:i:sP') . "\n";
?>

3. Carbon Date time package
if you are using Composer, Laravel, Symfony or any kinda framework this is the best way to get the date and time. Also this package extends DateTime class in php so you use all the method in Datetime class.
This in-built in frameworks like laravel so you don't have to install it separately.
printf("Right now is %s", Carbon::now()->toDateTimeString());
printf("Right now in Vancouver is %s", Carbon::now('America/Vancouver')); // automatically converted to string
$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();
// Carbon embed 823 languages:
echo $tomorrow->locale('fr')->isoFormat('dddd, MMMM Do YYYY, h:mm');
echo $tomorrow->locale('ar')->isoFormat('dddd, MMMM Do YYYY, h:mm');
$officialDate = Carbon::now()->toRfc2822String();
$howOldAmI = Carbon::createFromDate(1975, 5, 21)->age;
$noonTodayLondonTime = Carbon::createFromTime(12, 0, 0, 'Europe/London');
$internetWillBlowUpOn = Carbon::create(2038, 01, 19, 3, 14, 7, 'GMT');
if (Carbon::now()->isWeekend()) {
echo 'Party!';
}
echo Carbon::now()->subMinutes(2)->diffForHumans(); // '2 minutes ago'

Hope this helps and if you know any other way to get the date and time feel free to edit the answer.
Use:
$date = date('m/d/Y h:i:s a', time());
It works.
its very simple
echo $date = date('Y-m-d H:i:s');
$date = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
echo $date->format('d-m-Y H:i:s');
Update
//Also get am/pm in datetime:
echo $date->format('d-m-Y H:i:s a'); // output 30-12-2013 10:16:15 am
For the date format, PHP date() Function is useful.
echo date("d-m-Y H:i:sa");
This code will get the date and time of the server that the code runs on.
You can use this format also:
$date = date("d-m-Y");
Or
$date = date("Y-m-d H:i:s");
According to the article How to Get Current Datetime (NOW) with PHP, there are two common ways to get the current date. To get current datetime (now) with PHP, you can use the date class with any PHP version, or better the datetime class with PHP >= 5.2.
Various date format expressions are available here.
Example using date
This expression will return NOW in format Y-m-d H:i:s.
<?php
echo date('Y-m-d H:i:s');
?>
Example using datetime class
This expression will return NOW in format Y-m-d H:i:s.
<?php
$dt = new DateTime();
echo $dt->format('Y-m-d H:i:s');
?>
<?php
echo "<b>".date('l\, F jS\, Y ')."</b>";
?>
Prints like this
Sunday, December 9th, 2012
<?php
// Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the
// Mountain Standard Time (MST) Time Zone
$today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm
$today = date("m.d.y"); // 03.10.01
$today = date("j, n, Y"); // 10, 3, 2001
$today = date("Ymd"); // 20010310
$today = date('h-i-s, j-m-y, it is w Day'); // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // it is the 10th day.
$today = date("D M j G:i:s T Y"); // Sat Mar 10 17:16:18 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:18 m is month
$today = date("H:i:s"); // 17:16:18
$today = date("Y-m-d H:i:s"); // 2001-03-10 17:16:18 (the MySQL DATETIME format)
?>
Set your time zone:
date_default_timezone_set('Asia/Calcutta');
Then call the date functions
$date = date('Y-m-d H:i:s');
date(format, timestamp)
The date function returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given. In other words, timestamp is optional and defaults to the value of time().
And the parameters are -
format - Required. Specifies the format of the timestamp
timestamp - (Optional) Specifies a timestamp. Default is the current date and time
How to get a simple date
The required format parameter of the date() function specifies how to format the date (or time).
Here are some characters that are commonly used for dates:
d - Represents the day of the month (01 to 31)
m - Represents a month (01 to 12)
Y - Represents a year (in four digits)
l (lowercase 'L') - Represents the day of the week
Other characters, like "/", ".", or "-" can also be inserted between the characters to add additional formatting.
The example below formats today's date in three different ways:
<?php
echo "Today is " . date("Y/m/d") . "<br>";
echo "Today is " . date("Y.m.d") . "<br>";
echo "Today is " . date("Y-m-d") . "<br>";
echo "Today is " . date("l");
?>

The date format depends too:

Very simple
date_default_timezone_set('Asia/Kolkata');
$date = date('m/d/Y H:i:s', time());
If you want a different timescale, please use:
$tomorrow = mktime(0, 0, 0, date("m") , date("d")+1, date("Y"));
$lastmonth = mktime(0, 0, 0, date("m")-1, date("d"), date("Y"));
$nextyear = mktime(0, 0, 0, date("m"), date("d"), date("Y")+1);
date_default_timezone_set("Asia/Calcutta");
echo date("Y/m/d H:i:s");
date_default_timezone_set('Europe/Warsaw');
echo("<p class='time'>".date('H:i:s')."</p>");
echo("<p class='date'>".date('d/m/Y')."</p>");
You can use this code:
<?php
$currentDateTime = date('Y-m-d H:i:s');
echo $currentDateTime;
?>
I found that the simplest way of getting the current time in PHP is something like this.
//Prints out something like 10:00am Just be sure to set your timezone correctly.
date_default_timezone_set("America/Chicago");
$TIME = date('G:ia');
Another simple way is to take the timestamp of the current date and time. Use mktime() function:
$now = mktime(); // Return timestamp of the current time
Then you can convert this to another date format:
//// Prints something like: Thursday 26th of January 2017 01:12:36 PM
echo date('l jS \of F Y h:i:s A',$now);
More date formats are here:
http://php.net/manual/en/function.date.php
The best way to get the current time and date is by the date function in PHP:
$date = date('FORMAT'); // FORMAT E.g.: Y-m-d H:i:s
$current_date = date('Y-m-d H:i:s');
With the Unix timestamp:
$now_date = date('FORMAT', time()); // FORMAT Eg : Y-m-d H:i:s
To set the server time zone:
date_default_timezone_set('Asia/Calcutta');
A different time zone list is here.
Your Country Time Zone: List of Supported Timezones
date_default_timezone_set('Asia/Kolkata');
$dateYmd = date('Y-m-d');
echo "Current Year Month Day: $dateYmd";
Current Year Month Day: 2022-01-03
$datehms = date('h:i:s');
echo "Current Hour Minute Second: $datehms";
Current Hour Minute Second: 11:05:38
If you are Bangladeshi, and if you want to get the time of Dhaka then use this:
$date = new DateTime();
$date->setTimeZone(new DateTimeZone("Asia/Dhaka"));
$get_datetime = $date->format('d.m.Y H:i:s');
Normally, this function for date is useful for everyone: date("Y/m/d");
But time is something different, because the time function depends on either the PHP version or system date.
So probably use it like this to get our own time zone:
$date = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
echo $date->format('H:m:s');
This function shows the 24 hours time.

how to convert php date formats to GMT and vice versa?

i am new to php.
i want to write a function where i need user to input date in any date format including DST,into GMT format and again later back into the original entered format.please any body help me.
Although the gmdate functions are available. If you are using PHP 5.2 or greater, then consider using the DateTime object.
Here's code to switch to GMT
$date = new DateTime();
$date->setTimezone(new DateTimeZone('GMT'));
and back to the default timezone...
$date = new DateTime('2011-01-01', new DateTimeZone('GMT'));
$date->setTimezone(new DateTimeZone(date_default_timezone_get()));
Using the DateTime object lets your create a datetime, just like the procedural functions, except that you keep a reference to an instance.
e.g.
// Get a reference to Christmas of 2011, at lunch time.
$date = new DateTime('2011-12-25 13:00:00');
// Print the date for people to see, in whatever format we specify.
echo $date->format('D jS M y');
// Change the timezone to GMT.
$date->setTimezone(new DateTimeZone('GMT'));
// Now print the date/time it would in the GMT timezone
// as opposed to the default timezone it was created with.
echo $date->format('Y-m-d H:i:s');
// Just to show of some more, get the previous Sunday
$date->modify('previous Sunday');
There's a whole lot of functions you can use, that are much more readable that the procedural functions.
Explicit example of converting from a timezone to GMT
$melbourne = new DateTimeZone('Australia/Melbourne');
$gmt = new DateTimeZone('GMT');
$date = new DateTime('2011-12-25 00:00:00', $melbourne);
$date->setTimezone($gmt);
echo $date->format('Y-m-d H:i:s');
// Output: 2011-12-24 13:00:00
// At midnight on Christmas eve in Melbourne it will be 1pm on Christmas Eve GMT.
echo '<br/>';
// Convert it back to Australia/Melbourne
$date->setTimezone($melbourne);
echo $date->format('Y-m-d H:i:s');
Using your Asia/Kolkata to America/New_York
date_default_timezone_set('Asia/Kolkata');
$date = new DateTime('2011-03-28 13:00:00');
$date->setTimezone(new DateTimeZone('America/New_York'));
echo $date->format("Y-m-d H:i:s");
//Outputs: 2011-03-28 03:30:00
Use the gmdate function to convert to GMT time.
For example
$d = '2011-03-28 12:05:20';
$gmt = gmdate('Y-m-d H:i:s',strtotime($d));
// Convert local time to gmt
public function convertTime($timezone,$time){
$selectedtime = date("Y-m-d H:i",strtotime($time));
$date = new DateTime($selectedtime, new DateTimeZone($timezone));
$date->setTimezone(new DateTimeZone('GMT'));
$convertedtime = strtotime($date->format('Y-m-d H:i'));
return $convertedtime;
}

For a time-zone reference, see List of Supported Timezones.
Since PHP 5.2.0 you can use the DateTime() class:
use \Datetime;
$now = new DateTime();
echo $now->format('Y-m-d H:i:s'); // MySQL datetime format
echo $now->getTimestamp(); // Unix Timestamp -- Since PHP 5.3
And to specify the timezone:
$now = new DateTime(null, new DateTimeZone('America/New_York'));
$now->setTimezone(new DateTimeZone('Europe/London')); // Another way
echo $now->getTimezone();

This can be more reliable than simply adding or subtracting the number of seconds in a day or a month to a timestamp because of daylight saving time.
The PHP code
// Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the
// Mountain Standard Time (MST) Time Zone
$today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm
$today = date("m.d.y"); // 03.10.01
$today = date("j, n, Y"); // 10, 3, 2001
$today = date("Ymd"); // 20010310
$today = date('h-i-s, j-m-y, it is w Day'); // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // it is the 10th day.
$today = date("D M j G:i:s T Y"); // Sat Mar 10 17:16:18 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:18 m is month
$today = date("H:i:s"); // 17:16:18
$today = date("Y-m-d H:i:s"); // 2001-03-10 17:16:18 (the MySQL DATETIME format)
PHP's time() returns a current Unix timestamp. With this, you can use the date() function to format it to your needs.
$date = date('Format String', time());
As Paolo mentioned in the comments, the second argument is redundant. The following snippet is equivalent to the one above:
$date = date('Format String');
You can either use the $_SERVER['REQUEST_TIME'] variable (available since PHP 5.1.0) or the time() function to get the current Unix timestamp.
You can use both the $_SERVER['REQUEST_TIME'] variable or the time() function. Both of these return a Unix timestamp.
Most of the time these two solutions will yield the exact same Unix Timestamp. The difference between these is that $_SERVER['REQUEST_TIME'] returns the time stamp of the most recent server request and time() returns the current time. This may create minor differences in accuracy depending on your application, but for most cases both of these solutions should suffice.
Based on your example code above, you are going to want to format this information once you obtain the Unix Timestamp. Unformatted Unix time looks like: 1232659628
So in order to get something that will work, you can use the date() function to format it.
A good reference for ways to use the date() function is located in the PHP Manual.
As an example, the following code returns a date that looks like this: 01/22/2009 04:35:00 pm :
echo date("m/d/Y h:i:s a", time());
PHP's date function can do this job.
date()
Description:
string date(string $format [, int $timestamp = time()])
Returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given.
Examples:
$today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm
$today = date("m.d.y"); // 03.10.01
$today = date("j, n, Y"); // 10, 3, 2001
$today = date("Ymd"); // 20010310
$today = date('h-i-s, j-m-y, it is w Day'); // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // it is the 10th day.
$today = date("D M j G:i:s T Y"); // Sat Mar 10 17:16:18 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:18 m is month
$today = date("H:i:s"); // 17:16:18
$today = date("Y-m-d H:i:s"); // 2001-03-10 17:16:18 (the MySQL DATETIME format)
For the new PHP programmer might confuse why there are lot of method for to get current date and time and which one to use in their project.
1. date method (PHP 4, PHP 5, PHP 7)
This is the very common and very easiest way to get the date and time in php.
// set the default timezone to use. Available since PHP 5.1
date_default_timezone_set('UTC');
// Prints something like: Monday
echo date("l");
// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A');
// Prints: July 1, 2000 is on a Saturday
echo "July 1, 2000 is on a " . date("l", mktime(0, 0, 0, 7, 1, 2000));
/* use the constants in the format parameter */
// prints something like: Wed, 25 Sep 2013 15:28:57 -0700
echo date(DATE_RFC2822);
// prints something like: 2000-07-01T00:00:00+00:00
echo date(DATE_ATOM, mktime(0, 0, 0, 7, 1, 2000));

2. DateTime class (PHP 5 >= 5.2.0, PHP 7)
when you want to use PHP with OOP, this is the best way to get date and time.
<?php
// Specified date/time in your computer's time zone.
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:sP') . "\n";
// Specified date/time in the specified time zone.
$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";
// Current date/time in your computer's time zone.
$date = new DateTime();
echo $date->format('Y-m-d H:i:sP') . "\n";
// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";
// Using a UNIX timestamp. Notice the result is in the UTC time zone.
$date = new DateTime('#946684800');
echo $date->format('Y-m-d H:i:sP') . "\n";
// Non-existent values roll over.
$date = new DateTime('2000-02-30');
echo $date->format('Y-m-d H:i:sP') . "\n";
?>

3. Carbon Date time package
if you are using Composer, Laravel, Symfony or any kinda framework this is the best way to get the date and time. Also this package extends DateTime class in php so you use all the method in Datetime class.
This in-built in frameworks like laravel so you don't have to install it separately.
printf("Right now is %s", Carbon::now()->toDateTimeString());
printf("Right now in Vancouver is %s", Carbon::now('America/Vancouver')); // automatically converted to string
$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();
// Carbon embed 823 languages:
echo $tomorrow->locale('fr')->isoFormat('dddd, MMMM Do YYYY, h:mm');
echo $tomorrow->locale('ar')->isoFormat('dddd, MMMM Do YYYY, h:mm');
$officialDate = Carbon::now()->toRfc2822String();
$howOldAmI = Carbon::createFromDate(1975, 5, 21)->age;
$noonTodayLondonTime = Carbon::createFromTime(12, 0, 0, 'Europe/London');
$internetWillBlowUpOn = Carbon::create(2038, 01, 19, 3, 14, 7, 'GMT');
if (Carbon::now()->isWeekend()) {
echo 'Party!';
}
echo Carbon::now()->subMinutes(2)->diffForHumans(); // '2 minutes ago'

Hope this helps and if you know any other way to get the date and time feel free to edit the answer.
Use:
$date = date('m/d/Y h:i:s a', time());
It works.
its very simple
echo $date = date('Y-m-d H:i:s');
$date = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
echo $date->format('d-m-Y H:i:s');
Update
//Also get am/pm in datetime:
echo $date->format('d-m-Y H:i:s a'); // output 30-12-2013 10:16:15 am
For the date format, PHP date() Function is useful.
echo date("d-m-Y H:i:sa");
This code will get the date and time of the server that the code runs on.
You can use this format also:
$date = date("d-m-Y");
Or
$date = date("Y-m-d H:i:s");
According to the article How to Get Current Datetime (NOW) with PHP, there are two common ways to get the current date. To get current datetime (now) with PHP, you can use the date class with any PHP version, or better the datetime class with PHP >= 5.2.
Various date format expressions are available here.
Example using date
This expression will return NOW in format Y-m-d H:i:s.
<?php
echo date('Y-m-d H:i:s');
?>
Example using datetime class
This expression will return NOW in format Y-m-d H:i:s.
<?php
$dt = new DateTime();
echo $dt->format('Y-m-d H:i:s');
?>
<?php
echo "<b>".date('l\, F jS\, Y ')."</b>";
?>
Prints like this

<?php
// Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the
// Mountain Standard Time (MST) Time Zone
$today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm
$today = date("m.d.y"); // 03.10.01
$today = date("j, n, Y"); // 10, 3, 2001
$today = date("Ymd"); // 20010310
$today = date('h-i-s, j-m-y, it is w Day'); // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // it is the 10th day.
$today = date("D M j G:i:s T Y"); // Sat Mar 10 17:16:18 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:18 m is month
$today = date("H:i:s"); // 17:16:18
$today = date("Y-m-d H:i:s"); // 2001-03-10 17:16:18 (the MySQL DATETIME format)
?>
Set your time zone:
date_default_timezone_set('Asia/Calcutta');
Then call the date functions
$date = date('Y-m-d H:i:s');
date(format, timestamp)
The date function returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given. In other words, timestamp is optional and defaults to the value of time().
And the parameters are -
format - Required. Specifies the format of the timestamp
timestamp - (Optional) Specifies a timestamp. Default is the current date and time
How to get a simple date
The required format parameter of the date() function specifies how to format the date (or time).
Here are some characters that are commonly used for dates:
d - Represents the day of the month (01 to 31)
m - Represents a month (01 to 12)
Y - Represents a year (in four digits)
l (lowercase 'L') - Represents the day of the week
Other characters, like "/", ".", or "-" can also be inserted between the characters to add additional formatting.
The example below formats today's date in three different ways:
<?php
echo "Today is " . date("Y/m/d") . "<br>";
echo "Today is " . date("Y.m.d") . "<br>";
echo "Today is " . date("Y-m-d") . "<br>";
echo "Today is " . date("l");
?>

The date format depends too:
echo date("d/m/Y H:i:sa"); // 13/04/2017 19:38:15pm
Very simple
date_default_timezone_set('Asia/Kolkata');
$date = date('m/d/Y H:i:s', time());
If you want a different timescale, please use:
$tomorrow = mktime(0, 0, 0, date("m") , date("d")+1, date("Y"));
$lastmonth = mktime(0, 0, 0, date("m")-1, date("d"), date("Y"));
$nextyear = mktime(0, 0, 0, date("m"), date("d"), date("Y")+1);
date_default_timezone_set("Asia/Calcutta");
echo date("Y/m/d H:i:s");
date_default_timezone_set('Europe/Warsaw');
echo("<p class='time'>".date('H:i:s')."</p>");
echo("<p class='date'>".date('d/m/Y')."</p>");
You can use this code:
<?php
$currentDateTime = date('Y-m-d H:i:s');
echo $currentDateTime;
?>
I found that the simplest way of getting the current time in PHP is something like this.
//Prints out something like 10:00am Just be sure to set your timezone correctly.
date_default_timezone_set("America/Chicago");
$TIME = date('G:ia');
Another simple way is to take the timestamp of the current date and time. Use mktime() function:
$now = mktime(); // Return timestamp of the current time
Then you can convert this to another date format:
//// Prints something like: Thursday 26th of January 2017 01:12:36 PM
echo date('l jS \of F Y h:i:s A',$now);
More date formats are here:
http://php.net/manual/en/function.date.php
The best way to get the current time and date is by the date function in PHP:
$date = date('FORMAT'); // FORMAT E.g.: Y-m-d H:i:s
$current_date = date('Y-m-d H:i:s');
With the Unix timestamp:
$now_date = date('FORMAT', time()); // FORMAT Eg : Y-m-d H:i:s
To set the server time zone:
date_default_timezone_set('Asia/Calcutta');
A different time zone list is here.
Your Country Time Zone: List of Supported Timezones
date_default_timezone_set('Asia/Kolkata');
$dateYmd = date('Y-m-d');
echo "Current Year Month Day: $dateYmd";
Current Year Month Day: 2022-01-03
$datehms = date('h:i:s');
echo "Current Hour Minute Second: $datehms";
Current Hour Minute Second: 11:05:38
If you are Bangladeshi, and if you want to get the time of Dhaka then use this:
$date = new DateTime();
$date->setTimeZone(new DateTimeZone("Asia/Dhaka"));
$get_datetime = $date->format('d.m.Y H:i:s');
Normally, this function for date is useful for everyone: date("Y/m/d");
But time is something different, because the time function depends on either the PHP version or system date.
So probably use it like this to get our own time zone:
$date = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
echo $date->format('H:m:s');
This function shows the 24 hours time.
