Getting every given day of a month

Adamthenewbie

I am trying to make a function that would return all given days of a given month or a year. For instance I wanted to get all Mondays in a given month/year OR I wanted to get all Saturdays for a given month / year...

Function would be something like:

function getDaysOfMonth($month, $year, $day_of_week) {
// $month = 1 - 12
// $year = 2010, etc
// $day_of_week = 1,2,3, etc (1 for Monday, 2 for Tuesday, 7 for Sunday)

......

}

I'm puzzled by a "good way" to do this. If possible I only want the loop within the function to execute 5 times (as there would be most 5 "Mondays or Tuesdays, etc" in a given week. I can do this if I loop though the entire month but don't want it looping 30+ times... Hope someone can help,

Adam

http://se.php.net/manual/en/function.date.php has everything you need. In short

date('N', mktime(0,0,0, $month, 1, $year)) gives you day of week for first day in month.
basic arithmetics will give you the first day in month that matches the wanted week day.
date('t', mktime(...)) gives you number of days in month
run a while loop and increment day in month by 7 until day in month is > number of days in month.
