Add minutes to time

Question

I have the following code

$time = "12:00";
$duration = 90 . " minutes";
$arrival = strtotime("+" . $duration, $time);

Output should be 13:30.

I get the following error: "A non well formed numeric value encountered in" (line with $arrival)

What can I do?

Answer 1

The following code should work:

$time = strtotime("12:00");
$duration = "+90 minutes";
$arrival = strtotime($duration, $time);
print(date("H:i", $arrival));

Consider using PHP DateTime and DateInterval classes, like this:

$time = new \DateTime('now');
$time->add( new \DateInterval('PT90M') );

Try This Simple code :

<?php $time = strtotime('12:00');
