Code Example:

function ageLimit( $date, $reqAge ) {
    $date = strtotime( $date );
	if( $date !== false && $date !== -1 ) { // strtotime returns -1 < PHP 5.1.0         echo $diff = time() - $date;         return ( $diff / 31556926 > $reqAge ); // 31556926 seconds in a year
    }
    return false;
}

$req_age = ageLimit($date="26 March 1980", $age=25);
if($req_age){
	echo 'Age Limit Exceeded';
