Question

Assume today is Feb 21, 2011 ( Monday ). It is the third Monday of this month. If date is given as input, How can I know how many Mondays have passed before it?

In PHP, how to know how many mondays have passed in this month uptil today?

Answer 1

$now=time() + 86400;
if (($dow = date('w', $now)) == 0) $dow = 7; 
$begin = $now - (86400 * ($dow-1));

echo "Mondays: ".ceil(date('d', $begin) / 7)."<br/>";

works for me….

EDIT: includes today’s monday too
