Counting Specific "Day of the Week"s left in a month.

I need a php script that will count how many specific days of the week are left in a Month.

Eg. Today is Saturday, Sept 17. There are 2 Sundays left in this month.

I need to be able to count depending on specific days left.

This object oriented programming needs at least PHP 5.2. An example how to use it in the attached file.
function date_dow_left($dow)
{
    $datenow = new DateTime();
    $dateadd = clone $datenow;
    // if you want to skip today:
    $dateadd->add(new DateInterval('P1D'));

    $return = 0;
    while ($datenow->format('m') == $dateadd->format('m')) {
        if ($dateadd->format('N') == $dow) {
            $return++;
            $dateadd->add(new DateInterval('P1W'));
        } else {
            $dateadd->add(new DateInterval('P1D'));
        }
    }
    return $return;
}

You may be able to do this easily if you understand how PHP handles DATETIME information.  Look at the "fifth Friday" among the practical applications in this article.  If that does not make it immediately clear to you, please post back here with a clarifying question.

Try this:

function getDaysLeft($thisDate, $dNum) {
    // DEFINE NAMES
    $wkNames = Array(0=>"Sunday", 1=>"Monday", 2=>"Tuesday", 3=>"Wednesday", 4=>"Thursday", 5=>"Friday", 6=>"Saturday");
    $countMonth = 0;
    
    // SPLIT DATE
    $sDate = explode("/",$thisDate);
    $m = $sDate[0];
    $d = $sDate[1];
    $y = $sDate[2];
        
    // LOOP THROUGH REST OF MONTH AND RETURN DAYS
    while ($m == date("n",mktime(0,0,0,$m,$d,$y))) {
        $newDate = date("w",mktime(0,0,0,$m,$d,$y));
        if ($newDate == $dNum && isset($isDay)) { $countMonth++; echo $d . "|" . $m . "<BR>"; $d = $d + 7;}
        else { $d++; $isDay = 0; }
    }
    
    return "There are " . $countMonth . " " . $wkNames[$dNum] . "'s left in " . date('F',mktime(0,0,0,$m,$d,$y));
}

echo getDaysLeft("8/31/2011", 4);
