$end      = new DateTime('2013-08-30');
$interval = DateInterval::createFromDateString('1 day');
$period   = new DatePeriod($start, $interval, $end);

foreach ($period as $dt) {
    if ($dt->format("N") == 2 || $dt->format("N") == 4) {
        echo $dt->format("l Y-m-d") . "<br>\n";
    }
}

What this code does:

1. Creates a starting date object using DateTime.
2. Creates a starting date object using DateTime.
3. Creates a DateInterval object to represent our interval of time to iterate through. In this case 1 day.
4. Creates a DatePeriod object to manage these objects.
5. Using DatePeriod, it iterates through the date starting with the starting date and ending at the end date. We use DateTime::format() with the N parameter to get the day number of the week. If the day number of the week is 2 (Tuesday) or 4 (Thursday) echo out it's value.
