[RESOLVED] calculate times and differences

[condoug]

Hi all

I have 2 variables each containing time in the following format for example:

$var1 = '14:04:54';
$var2 = '14:40:35';

I have a 3rd variable which is set as number of minutes in integer form:

$var3 = 60;

Now I need to calculate if the difference between $var1 and $var2 is greater than $var3 - any ideas how this would be written?

Thank you for reading.

You could try something like:

<?php
$var1 = '14:04:54';
$var2 = '14:40:35';
$var3 = 60;

if (abs(strtotime($var1) - strtotime($var2)) > ($var3 * 60)) {
    echo 'Out of range.';
} else {
    echo 'Within range.';
}
?>

Alternatively, you could use explode(), then manually compute the time for $var1 and $var2 in seconds.

By the way, $var is a rather poor name for a variable.

Thanks laserlight, that works fine.

incidentally i called the variables $var for simplicity when posting, my real naming conventions are more explanatory!
