Question

I have two dates in the format below:

Start Date = 30-10-2009

End Date = 30-11-2009

How, with PHP could I calculate the seconds between these two dates?

Answer 1

Parse the two dates into Unix timestamps using strtotime, then get the difference:

$firstTime = strtotime("30-10-2009");
$secondTime = strtotime("30-11-2009");
$diff = $secondtime - $firstTime;
