I am looking for a way to determine the week of the year if i have a date.

 

i know that

date("W"); give me the week Number

but not sure how to determine the week based on the date

That's tricky because it's a UNIX timestamp.  Look up php unix timestamp and you might be able to find some great resources

Actually if u have a date, lest say 5/21/2007, u can use date() and mktime() to calculate the week. Im giving a simple example:

 

<?php
$date = '5/21/2007';
list($month, $day, $year) = explode('/', $date);
$week = date('W', mktime(0, 0, 0, $month, $day, $year));
echo $week;
?>

 

Hope it makes sense and helps.
