A Tricky Time Calculation

Hi,

Given the time range: 09:15 - 17:30 how can I tell how many 15 minute
intervals occur between these two times? Obviously here I can work it out,
but I need a calculation that will perform the maths for any two time
ranges...

Thanks for your help

$time1 = '09:15';
$time2 = '17:30';
$intervals = floor((strtotime($time2) - strtotime($time1)) / 900);
