Get the timestamp of exactly one week ago in PHP? - php

I need to calculate the timestamp of exactly 7 days ago using PHP, so if it's currently March 25th at 7:30pm, it would return the timestamp for March 18th at 7:30pm.
Should I just subtract 604800 seconds from the current timestamp, or is there a better method?

strtotime("-1 week")

strtotime is your friend
echo strtotime("-1 week");

http://php.net/strtotime
echo strtotime("-1 week");

There is the following example on PHP.net
<?php
$nextWeek = time() + (7 * 24 * 60 * 60);
// 7 days; 24 hours; 60 mins; 60secs
echo 'Now: '. date('Y-m-d') ."\n";
echo 'Next Week: '. date('Y-m-d', $nextWeek) ."\n";
// or using strtotime():
echo 'Next Week: '. date('Y-m-d', strtotime('+1 week')) ."\n";
?>
Changing + to - on the first (or last) line will get what you want.

From PHP 5.2 you can use DateTime:
$timestring="2015-03-25";
$datetime=new DateTime($timestring);
$datetime->modify('-7 day');
echo $datetime->format("Y-m-d"); //2015-03-18
Instead of creating DateTime with string, you can setTimestamp directly on object:
$timestamp=1427241600;//2015-03-25
$datetime=new DateTime();
$datetime->setTimestamp($timestamp);
$datetime->modify('-7 day');
echo $datetime->format("Y-m-d"); //2015-03-18

<?php
$before_seven_day = $date_timestamp - (7 * 24 * 60 * 60)
// $date_timestamp is the date from where you found to find out the timestamp.
?>
you can also use the string to time function for converting the date to timestamp. like
strtotime(23-09-2013);

how to get date after 2 days from the given time in php

i want to find out the date after days from the given time.
for example. we have date 29 may 2015
and i want to cqlculate the date after 2 days of 25 may 2015
$Timestamp = 1432857600 (unix time of 29-05-2015)
i have tried to do it with following code but it is not working
$TotalTimeStamp = strtotime('2 days', $TimeStamp);
Missed the + - strtotime('2 days', $TimeStamp); .
Add the + to + 2 days.
Use date & strtotime for this - You can try this -
echo date('d-m-Y',strtotime(' + 2 day', strtotime('2015-05-16')));
$Timestamp & $TimeStamp are not same(may be typo). For your code -
$Timestamp = strtotime(date('Y-m-d'));
$TotalTimeStamp = strtotime('+ 2 days', $Timestamp);
echo date('d-m-Y', $TotalTimeStamp);
Php does have a pretty OOP Api to deal with date and time.
This will create a \DateTime instance using as reference the 25 May 2015 and then you can call the modify method on that instance to add 2 days.
$date = new \DateTime('2015-05-25');
$date->modify('+2 day');
echo $date->format('Y-m-d');
You may find this resource useful:
http://code.tutsplus.com/tutorials/dates-and-time-the-oop-way--net-35395
You can also just add seconds to your timestamp if you have a timestamp ready:
$NewDateStamp = $Timestamp + (60*60*24 * 2);
In the above, sec * min * hours = day -- or 86400 seconds. * 2 = 2 days.
In PHP 5 you can also use D
<?php
$date = date_create('2015-05-16');
date_add($date, date_interval_create_from_date_string('2 days'));
echo date_format($date, 'Y-m-d');
?>
OR
<?php
$date = new DateTime('2015-05-16');
$date->add(new DateInterval('2 days'));
echo $date->format('Y-m-d') . "\n";
?>

PHP mktime() is returning wrong date

im doing some stuff with mktime, i need to add the next date with 30 days more but its returning me 1970-01-30 date, what im doing wrong ?
$strtime=strtotime("2013-10-04");
$fecha=date("Y-m-d",$strtime);
echo $fecha."<br />";
$nueva_fecha=mktime(0,0,0,date("n",$fecha),date("j",$fecha)+30,date("Y",$fecha));
echo date("Y-m-d",$nueva_fecha)."<br />";
Result:
2013-10-04
1970-01-30
Date is looking for a timestamp as it's 2nd parameter, not a string value representing this. Updated to pass it $strtime instead.
$strtime=strtotime("2013-10-04");
$fecha=date("Y-m-d",$strtime); // <-- Unnecessary unless you want to echo the value.
echo $fecha."<br />";
$nueva_fecha=mktime(0,0,0,date("n",$strtime),date("j",$strtime)+30,date("Y",$strtime));
echo date("Y-m-d",$nueva_fecha)."<br />";
Output:
2013-10-04
2013-11-03
You can just use the following function to add 30 days to the date you put in:
$date = strtotime("2013-10-04");
$new_date = strtotime("+30 days", $date);
or simply to the current date:
$new_date = strototime("+30 days", time());
If you already have strtotime, why plus on date ? Instead you could've used + (30 days in seconds) OR simply the feature they offer you + 1 day check answer: adding one day to a date
strtotime('2013-10-04 + 30 days');
This will print 2013-11-03:
date('Y-m-d', strtotime('2013-10-04 + 30 days'))
you can try this:
echo strtotime("+1 day"), "\n";
echo strtotime("+30 day",strtotime(date('D, d M Y'))), "\n";
this will add 30 days to the current date.
Also strtotime is very usefull you can use it for weekly,monthly and yearly.
You can use this also
<?php
$date = date("Y/m/d"); // example date in yyyy/mm/dd format
$unix_time = strtotime( $date ); // covert date to unix time
$sec_in_30_days = 60 * 60 * 24 * 30; // 60 seconds * 60 minutes * 24 hours * 30 days
$new_unix_time = $unix_time + $sec_in_30_days; // add 30 days to unix time
$date_in_30_days = date( 'Y/m/d', $new_unix_time ); // convert new unix time to date
// Output results:
echo 'original current date: ' . $date . '<br />';
echo '<br />';
echo 'new date: ' . $date_in_30_days . '<br />';
?>
Output will be
original current date: 2013/10/04
new date: 2013/11/03

PHP - Adding 7 days to a date the proper way [duplicate]

I want to add number of days to current date:
I am using following code:
$i=30;
echo $date = strtotime(date("Y-m-d", strtotime($date)) . " +".$i."days");
But instead of getting proper date i am getting this:
2592000
Please suggest.
This should be
echo date('Y-m-d', strtotime("+30 days"));
strtotime
expects to be given a string containing a US English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.
while date
Returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given.
See the manual pages for
http://www.php.net/manual/en/function.strtotime.php
http://www.php.net/manual/en/function.date.php
and their function signatures.
This one might be good
function addDayswithdate($date,$days){
$date = strtotime("+".$days." days", strtotime($date));
return date("Y-m-d", $date);
}
$date = new DateTime();
$date->modify('+1 week');
print $date->format('Y-m-d H:i:s');
or print date('Y-m-d H:i:s', mktime(date("H"), date("i"), date("s"), date("m"), date("d") + 7, date("Y"));
$today=date('d-m-Y');
$next_date= date('d-m-Y', strtotime($today. ' + 90 days'));
echo $next_date;
You can add like this as well, if you want the date 5 days from a specific date :
You have a variable with a date like this (gotten from an input or DB or just hard coded):
$today = "2015-06-15"; // Or can put $today = date ("Y-m-d");
$fiveDays = date ("Y-m-d", strtotime ($today ."+5 days"));
echo $fiveDays; // Will output 2015-06-20
Keep in mind, the change of clock changes because of daylight saving time might give you some problems when only calculating the days.
Here's a little php function which takes care of that:
function add_days($date, $days) {
$timeStamp = strtotime(date('Y-m-d',$date));
$timeStamp+= 24 * 60 * 60 * $days;
// ...clock change....
if (date("I",$timeStamp) != date("I",$date)) {
if (date("I",$date)=="1") {
// summer to winter, add an hour
$timeStamp+= 60 * 60;
} else {
// summer to winter, deduct an hour
$timeStamp-= 60 * 60;
} // if
} // if
$cur_dat = mktime(0, 0, 0,
date("n", $timeStamp),
date("j", $timeStamp),
date("Y", $timeStamp)
);
return $cur_dat;
}
You could also try:
$date->modify("+30 days");
You can do it by manipulating the timecode or by using strtotime(). Here's an example using strtotime.
$data['created'] = date('Y-m-d H:i:s', strtotime("+1 week"));
You can use strtotime()
$data['created'] = date('Y-m-d H:m:s', strtotime('+1 week'));
I know this is an old question, but for PHP <5.3 you could try this:
$date = '05/07/2013';
$add_days = 7;
$date = date('Y-m-d',strtotime($date) + (24*3600*$add_days)); //my preferred method
//or
$date = date('Y-m-d',strtotime($date.' +'.$add_days.' days');
You could use the DateTime class built in PHP. It has a method called "add", and how it is used is thoroughly demonstrated in the manual: http://www.php.net/manual/en/datetime.add.php
It however requires PHP 5.3.0.
$date = "04/28/2013 07:30:00";
$dates = explode(" ",$date);
$date = strtotime($dates[0]);
$date = strtotime("+6 days", $date);
echo date('m/d/Y', $date)." ".$dates[1];
You may try this.
$i=30;
echo date("Y-m-d",mktime(0,0,0,date('m'),date('d')+$i,date('Y')));
Simple and Best
echo date('Y-m-d H:i:s')."\n";
echo "<br>";
echo date('Y-m-d H:i:s', mktime(date('H'),date('i'),date('s'), date('m'),date('d')+30,date('Y')))."\n";
Try this
//add the two day
$date = "**2-4-2016**"; //stored into date to variable
echo date("d-m-Y",strtotime($date.**' +2 days'**));
//print output
**4-4-2016**
Use this addDate() function to add or subtract days, month or years (you will need the auxiliar function reformatDate() as well)
/**
* $date self explanatory
* $diff the difference to add or subtract: e.g. '2 days' or '-1 month'
* $format the format for $date
**/
function addDate($date = '', $diff = '', $format = "d/m/Y") {
if (empty($date) || empty($diff))
return false;
$formatedDate = reformatDate($date, $format, $to_format = 'Y-m-d H:i:s');
$newdate = strtotime($diff, strtotime($formatedDate));
return date($format, $newdate);
}
//Aux function
function reformatDate($date, $from_format = 'd/m/Y', $to_format = 'Y-m-d') {
$date_aux = date_create_from_format($from_format, $date);
return date_format($date_aux,$to_format);
}
Note: only for php >=5.3
Use the following code.
<?php echo date('Y-m-d', strtotime(' + 5 days')); ?>
Reference has found from here - How to Add Days to Current Date in PHP
Even though this is an old question, this way of doing it would take of many situations and seems to be robust. You need to have PHP 5.3.0 or above.
$EndDateTime = DateTime::createFromFormat('d/m/Y', "16/07/2017");
$EndDateTime->modify('+6 days');
echo $EndDateTime->format('d/m/Y');
You can have any type of format for the date string and this would work.
//Set time zone
date_default_timezone_set("asia/kolkata");
$pastdate='2016-07-20';
$addYear=1;
$addMonth=3;
$addWeek=2;
$addDays=5;
$newdate=date('Y-m-d', strtotime($pastdate.' +'.$addYear.' years +'.$addMonth. ' months +'.$addWeek.' weeks +'.$addDays.' days'));
echo $newdate;
Do not use php's date() function, it's not as accurate as the below solution and furthermore it is unreliable in the future.
Use the DateTime class
<?php
$date = new DateTime('2016-06-06'); // Y-m-d
$date->add(new DateInterval('P30D'));
echo $date->format('Y-m-d') . "\n";
?>
The reason you should avoid anything to do with UNIX timestamps (time(), date(), strtotime() etc) is that they will inevitably break in the year 2038 due to integer limitations.
The maximum value of an integer is 2147483647 which converts to Tuesday, 19 January 2038 03:14:07 so come this time; this minute; this second; everything breaks
Source
Another example of why I stick to using DateTime is that it's actually able to calculate months correctly regardless of what the current date is:
$now = strtotime('31 December 2019');
for ($i = 1; $i <= 6; $i++) {
echo date('d M y', strtotime('-' . $i .' month', $now)) . PHP_EOL;
}
You'd get the following sequence of dates:
31 December
31 November
31 October
31 September
31 August
31 July
31 June
PHP conveniently recognises that three of these dates are illegal and converts them into its best guess, leaving you with:
01 Dec 19
31 Oct 19
01 Oct 19
31 Aug 19
31 Jul 19

How do I add 24 hours to a unix timestamp in php?

I would like to add 24 hours to the timestamp for now. How do I find the unix timestamp number for 24 hours so I can add it to the timestamp for right now?
I also would like to know how to add 48 hours or multiple days to the current timestamp.
How can I go best about doing this?
You probably want to add one day rather than 24 hours. Not all days have 24 hours due to (among other circumstances) daylight saving time:
strtotime('+1 day', $timestamp);
A Unix timestamp is simply the number of seconds since January the first 1970, so to add 24 hours to a Unix timestamp we just add the number of seconds in 24 hours. (24 * 60 *60)
time() + 24*60*60;
Add 24*3600 which is the number of seconds in 24Hours
Unix timestamp is in seconds, so simply add the corresponding number of seconds to the timestamp:
$timeInFuture = time() + (60 * 60 * 24);
You could use the DateTime class as well:
$timestamp = mktime(15, 30, 00, 3, 28, 2015);
$d = new DateTime();
$d->setTimestamp($timestamp);
Add a Period of 1 Day:
$d->add(new DateInterval('P1D'));
echo $d->format('c');
See DateInterval for more details.
As you have said if you want to add 24 hours to the timestamp for right now then simply you can do:
<?php echo strtotime('+1 day'); ?>
Above code will add 1 day or 24 hours to your current timestamp.
in place of +1 day you can take whatever you want, As php manual says strtotime can Parse about any English textual datetime description into a Unix timestamp.
examples from the manual are as below:
<?php
echo strtotime("now"), "\n";
echo strtotime("10 September 2000"), "\n";
echo strtotime("+1 day"), "\n";
echo strtotime("+1 week"), "\n";
echo strtotime("+1 week 2 days 4 hours 2 seconds"), "\n";
echo strtotime("next Thursday"), "\n";
echo strtotime("last Monday"), "\n";
?>
$time = date("H:i", strtotime($today . " +5 hours +30 minutes"));
//+5 hours +30 minutes Time Zone +5:30 (Asia/Kolkata)
