[SOLVED] counting weeks?

[php_b34st]

How would I count how many weeks it has been since a set starting date?

 

if the starting date was sat 16th august and I check on sat 6th september it should be week 4.

 

thanks in advance

if you convert each date to a timestamp and subtract the earlier one from the later one, that will give you the number of seconds between the dates. you can then divide by 60 for minutes, 60 again for hours, 24 for days, then 7 for weeks between. i'd probably use mktime() or strtotime() to make the timestamps.
