Get the timestamp of exactly one week ago in PHP?
59,552
Solution 1
strtotime("-1 week")
Solution 2
strtotime is your friend
echo strtotime("-1 week");
Solution 3
echo strtotime("-1 week");
Solution 4
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

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?
