How can I get the last day of the month in PHP?

Answer 1

Here is a complete function:

public function get_number_of_days_in_month($month, $year) {
    // Using first day of the month, it doesn't really matter
    $date = $year."-".$month."-1";
    return date("t", strtotime($date));
}

This would output following:

echo get_number_of_days_in_month(2,2014);

Output: 28
