I have a date string in sql format (eg 2017-08-05) and will like to convert it to get the previous weekday.
I know that there is the strtotime method where I can get the previous weekday from a specific date, such as:
date("Y m d",strtotime("-2 Weekday", strtotime("2017-08-05")));
Is there a better (prettier) way to do this? Or is this the PHP way?
The same can be achieved with just one call to strtotime:
date("Y m d", strtotime("2017-08-05 -2 Weekday"))
By using Carbon
Carbon::parse('2017-08-05')->previousWeekday()
Or if you want sameway
Carbon::parse('2017-08-05')->subWeekday(2)->toDateString()
you can create a carbon
carbon::parse('2012-08-05')->previousWeekday();
No better way then this...
Try this:
// create a new instance of DateTimeImmutable
$date = new \DateTimeImmutable('2017-08-05');
// create a one-day interval
$interval = new \DateInterval('P1D');
// subtract the interval, and keep doing that while the day before is not a weekday
do {
$date = $date->sub($interval);
} while (5 < $date->format('N'));
echo $date->format('Y-m-d');
For reference, see:
http://php.net/manual/en/class.datetimeimmutable.php
http://php.net/manual/en/class.dateinterval.php

So I've checked the list of supported time zones in PHP and I was wondering how could I include them in the date() function?
Thanks!
I don't want a default timezone, each user has their timezone stored in the database, I take that timezone of the user and use it. How? I know how to take it from the database, not how to use it, though.
For such task, you should really be using PHP's DateTime class. Please ignore all of the answers advising you to use date() or date_set_time_zone, it's simply bad and outdated.
I'll use pseudocode to demonstrate, so try to adjust the code to suit your needs.
Assuming that variable $tz contains string name of a valid time zone and variable $timestamp contains the timestamp you wish to format according to time zone, the code would look like this:
$tz = 'Europe/London';
$timestamp = time();
$dt = new DateTime("now", new DateTimeZone($tz)); //first argument "must" be a string
$dt->setTimestamp($timestamp); //adjust the object to correct timestamp
echo $dt->format('d.m.Y, H:i:s');
DateTime class is powerful, and to grasp all of its capabilities - you should devote some of your time reading about it at php.net. To answer your question fully - yes, you can adjust the time zone parameter dynamically (on each iteration while reading from db, you can create a new DateTimeZone() object).
If I understood correct,You need to set time zone first like:
date_default_timezone_set('UTC');
And than you can use date function:
// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A');
The answer above caused me to jump through some hoops/gotchas, so just posting the cleaner code that worked for me:
$dt = new DateTime();
$dt->setTimezone(new DateTimeZone('America/New_York'));
$dt->setTimestamp(123456789);
echo $dt->format('F j, Y # G:i');
Use the DateTime class instead, as it supports timezones. The DateTime equivalent of date() is DateTime::format.
An extremely helpful wrapper for DateTime is Carbon - definitely give it a look.
You'll want to store in the database as UTC and convert on the application level.
It should like this:
date_default_timezone_set('America/New_York');
U can just add, timezone difference to unix timestamp.
Example for Moscow (UTC+3)
echo date('d.m.Y H:i:s', time() + 3 * 60 * 60);
Try this. You can pass either unix timestamp, or datetime string
public static function convertToTimezone($timestamp, $fromTimezone, $toTimezone, $format='Y-m-d H:i:s')
{
$datetime = is_numeric($timestamp) ?
DateTime::createFromFormat ('U' , $timestamp, new DateTimeZone($fromTimezone)) :
new DateTime($timestamp, new DateTimeZone($fromTimezone));
$datetime->setTimezone(new DateTimeZone($toTimezone));
return $datetime->format($format);
}
this works perfectly in 2019:
date('Y-m-d H:i:s',strtotime($date. ' '.$timezone));
I have created this very straightforward function, and it works like a charm:
function ts2time($timestamp,$timezone){ /* input: 1518404518,America/Los_Angeles */
$date = new DateTime(date("d F Y H:i:s",$timestamp));
$date->setTimezone(new DateTimeZone($timezone));
$rt=$date->format('M d, Y h:i:s a'); /* output: Feb 11, 2018 7:01:58 pm */
return $rt;
}
I have tried the answers based on the DateTime class. While they are working, I found a much simpler solution that makes a DateTime object timezone aware at the time of creation.
$dt = new DateTime("now", new DateTimeZone('Asia/Jakarta'));
echo $dt->format("Y-m-d H:i:s");
This returns the current local time in Jakarta, Indonesia.
Not mentioned above. You could also crate a DateTime object by providing a timestamp as string in the constructor with a leading # sign.
$dt = new DateTime('#123456789');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('F j, Y - G:i');
See the documentation about compound formats:
https://www.php.net/manual/en/datetime.formats.compound.php
Based on other answers I built a one-liner, where I suppose you need current date time. It's easy to adjust if you need a different timestamp.
$dt = (new DateTime("now", new DateTimeZone('Europe/Rome')))->format('d-m-Y_His');
If you use Team EJ's answer, using T in the format string for DateTime will display a three-letter abbreviation, but you can get the long name of the timezone like this:
$date = new DateTime('2/3/2022 02:11:17');
$date->setTimezone(new DateTimeZone('America/Chicago'));
echo "\n" . $date->format('Y-m-d h:i:s T');
/* Displays 2022-02-03 02:11:17 CST "; */
$t = $date->getTimezone();
echo "\nTimezone: " . $t->getName();
/* Displays Timezone: America/Chicago */
$now = new DateTime();
$now->format('d-m-Y H:i:s T')
Will output:
29-12-2021 12:38:15 UTC
I had a weird problem on a hosting. The timezone was set correctly, when I checked it with the following code.
echo ini_get('date.timezone');
However, the time it returned was UTC.
The solution was using the following code since the timezone was set correctly in the PHP configuration.
date_default_timezone_set(ini_get('date.timezone'));
You can replace database value in date_default_timezone_set function,
date_default_timezone_set(SOME_PHP_VARIABLE);
but just needs to take care of exact values relevant to the timezones.
I want to store a specific date in a variable. If stored like $x="01/01/2016" it is acting as a string from which I cannot extract a part, like from getdate() year, month, day of the month, etc.
Use the DateTime object:
$dateTime = new DateTime('2016/01/01');
To get only parts of the date you can use the format method:
echo $dateTime->format('Y'); // it will display 2016
If you need to create it from the format you wrote in the question, then you can use the factory method createFromFormat:
$dateTime = DateTime::createFromFormat('d/m/Y', '01/01/2016');
echo $dateTime->format('Y/m/d');
This is work for me
$date = '20/May/2015:14:00:01';
$dateInfo = date_parse_from_format('d/M/Y:H:i:s', $date);
$unixTimestamp = mktime(
$dateInfo['hour'], $dateInfo['minute'], $dateInfo['second'],
$dateInfo['month'], $dateInfo['day'], $dateInfo['year'],
$dateInfo['is_dst']
);
this is what you are looking for http://php.net/manual/en/class.datetime.php
You can use $myDate = new DateTime('01/01/2016'); to declare date. To get year, month and date from the specified date, use echo $myDate->format('d m Y');
Change the format based on your need. To know more about date format refer
I have a problem.
I have a certain date/time (A), which is put in a variable. Lets say its May 06 2014 14:26.
I want to compare this date/time with file's modification date/time (B), and if it is the same, I put the file's modification date/time (B) in variable too.
The thing is, I cant get exactly the same date on file (B). So, I want that it would add 5 minutes difference. For example, if file (B) has modification date May 06 2014 14:28, it will be put in a variable. Or if it has modification date May 06 2014 14:22, it will be put in a variable too.
If it helps, I am using date("F d Y H:i",$file['filetime']) command to get the modification date of the file.
Any possibility to do this? Thanks in advance.
If something is unclear, just tell me. I'm new here, so might be hard to explain things correctly.
Maybe, it helps:
$datetimeA = strtotime($file1['filetime']);
$datetimeB = strtotime($file2['filetime']);
$interval = abs($datetimeA - $datetimeB);
$minutes = round($interval / 60);
if ($minutes > 5) {
//do some magic here
}
If $file['filetime'] is a timestamp already, then You can use it without calling strtotime().
With the DateTime class, it is done in a few lines :
$datetime1 = new DateTime('2009-10-13 10:00:00');
$datetime2 = new DateTime('2009-10-13 10:20:00');
$interval = $datetime1->diff($datetime2);
$yourIntervalle = $interval->format('%i minutes'));
i'd either directly use unix-timestamps or convert A and B to Unix Timestamps (e.g. using strtotime) and compare them based on your requirements.
if you have access to the file directly you could even use filemtime to directly get the last modified time as an unix timestamp.
Guess this is what you're looking for, if your problem is just to add 5 minutes:
$dateB = new DateTime('2014-05-06 14:26:00');
$interval = new DateInterval('PT5M');
$dateB->add($interval);
print_r($dateB);
PHPSandbox: http://sandbox.onlinephpfunctions.com/code/9f9a2ee40f09f953c796c9c2dd7e15ad62b45772
Also, look at DateInterval to understand a little more:
http://www.php.net/manual/en/dateinterval.construct.php
you can do like. if you want to minus 5 minutes from the date
$given_date = 'May 06 2014 14:28';
$date = new DateTime($given_date);
//subtract 5 minutes from the date
$new_date = $date->sub(new DateInterval('PT' . '5' . 'M'));
echo $new_date->format('F d Y H:i');
if you want to add 5 minutes then change
//add 5 minutes to the date
$new_date = $date->add(new DateInterval('PT' . '5' . 'M'));
First of all, i think you need to compare the two date/time by the method strtotime. With that you can compare the two date.
Then, you just need to make one or two insert in your database if i understand correctly with a If/Else method.
Hope it helps!
I' am trying to convert the date of next 7 days into timestamp so that I can compare against my date timestamp in database to get some results.
This function is used to get the next 7 days from today
$next_date = date("d/m/Y", strtotime("7 day"))
Output
30/04/2014
Now I' am again running strtotime() on $next_date variable who holds the next 7days and converting to timestamp.
echo strtotime($next_date);
This is not working. I followed this stackoverflow answer and few others.
As an alternative suggestion you could look at PHP's internal DateTime() and DateInterval() classes. It makes it a bit easier to convert between formats and do date/time addition and subtraction imho. DateInterval requires at least PHP version 5.3.
An example:
// create a current DateTime
$currDate = new DateTime();
// copy the current DateTime and
// add an interval of 7 days
$nextDate = clone $currDate;
$nextDate->add(new DateInterval('P7D'));
// both objects are easily converted to timestamps
echo $currDate->getTimestamp(); // e.g: 1398296728
echo $nextDate->getTimestamp(); // e.g: 1398901528
// and both can be easily formatted in other formats
echo $currDate->format('d/m/Y'); // e.g: 24/04/2014
echo $nextDate->format('d/m/Y'); // e.g: 01/05/2014
EDIT
For completeness, here's another example of how you can add seven days to a DateTime object:
$now = new DateTimeImmutable();
$then = $now->modify('+7 days');
var_dump($now->format('Y-m-d'), $then->format('Y-m-d'));
Yields:
string(10) "2016-05-24"
string(10) "2016-05-31"
You can also use DateTime - the difference in this use case is that DateTime::modify() will modify the instance $now where DateTimeImmutable::modify() will return a new DateTimeImmutable object - so if you need to create a new object whilst retaining the old one, it's probably the most succinct approach.
Hope this helps :)
http://www.php.net/manual/en/datetime.construct.php
http://www.php.net/manual/en/dateinterval.construct.php
Just store the value from strtotime first?
$timestamp_in_7_days = strtotime('7 day');
$next_date = date('d/m/Y', $timestamp_in_7_days);
There is no need to throw the time back and forth between unix timestamp and date-format.
I have a date in this format:
24-12-2010 // DAY - MONTH - YEAR
I need to get it in this format:
1995-12-31T23:59:59.999Z // The Z is for the TimeZone I think.
Check this link out:
http://lucene.apache.org/solr/api/org/apache/solr/schema/DateField.html
The above link is the way I need the date.
I am using PHP now, so this needs to be with PHP.
How can I convert these dates the easiest way?
Thanks
That is an ISO8601 format date; the following is what you want.
gmdate('Y-m-d\TH:i:s\Z', strtotime($date_value));
You can do something like that:
$dateTime = new DateTime($myDate);
$formatted = $dateTime->format("Y-m-d\TH:i:s.z\Z");
The mentioned solution with:
$dateTime->format(DateTime::W3C);
$dateTime->format(DateTime::ISO8601);
does return strings like:
2012-11-28T17:21:11+0100
which cannot be parsed, at least with newer Solr versions.
I wouldn't use gmdate if you need to support timezones. The DateTime implementation is well done, and is also available for functional programming.
http://php.net/manual/en/class.datetime.php
http://php.net/manual/en/ref.datetime.php
You can use the DateTime class
$dateTime = new DateTime();
$dateTime.setDate(24, 12, 2010);
$output = $dateTime.format(DateTime::W3C);
// Output now is your date in W3C format.
use the date ( string $format [, int $timestamp ] ) function of php!
In second paramter use http://php.net/manual/en/function.strtotime.php to get the timestamp from strings
$date = strtotime('24-12-2010');
$new_date = gmDate("Y-m-d\TH:i:s.z\Z",$date);
