Assuming a week starts on Monday. To calculate the week number of the current date starting from a
specified date, use this function:
<?php
function weekcounter($start_date)
{
$start_date = strtotime($start_date);
$today = strtotime(date('d-m-Y'));
$week = 1;
while($start_date < $today) {
$start_date = strtotime('next Monday', $start_date);
$week++;
}
return $week;
}
?>
Example:
//now = 14-07-2008
echo weekcounter('01-07-2008'); //prints 3
echo weekcounter('01-06-2008'); //prints 8 instead of 7; because 1st jun is a Sunday so it
is week 1 and 2nd june is week 2. Feel free to tweak.
