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

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

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

Answer 2

If you're looking for how to display the time in a human readable format, these examples will help:

$livetime = date('H:i:s', time() - 3600); // 16:00:00
$livetime = date('g:iA ', time() - 3600); // 4:00PM

Answer 3

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

See time PHP function for more information.

Answer 4

convert your date to strtotime and then subtract one hour from it

$now =  date('Y-m-d H:i:s');
$time   = strtotime($now);
$time   = $time - (60*60); //one hour
$beforeOneHour = date("Y-m-d H:i:s", $time);

Answer 5

You could use the date_create function along with the date_sub function like I have shown here below: -

$currentTime = date_create(now());
$modifyTime = date_sub($currentTime,date_interval_create_from_date_string("1 hour"));
$liveTime = $modifyTime->format('Y-m-d H:i:s');
