Create Variable in PHP Equal to Current Time Minus One Hour

Question

In PHP, how could I create a variable called $livetime that equals the current time minus 1 hour?

Answer 1

$livetime = time() - 3600; // 3600 seconds in 1 hour : 60 seconds (1 min) * 60 (minutes in hour)

See time PHP function for more information.

Answer 2

Another way - without all the math and, in my opinion, reads better.

$hour_ago = strtotime('-1 hour');

Answer 3

Here you go:

<?php

$now = time();
echo strftime("%c",$now) . "\n";
$livetime = $now-3600;
echo strftime("%c",$livetime) . "\n";
?>
