Answer 1

This should get you started:

$dt = new DateTime('first Monday of this month');
echo $dt->format('l m d');

See it in action

Answer 2

You can use strotime() , like so:

function getDateFromDay($day) {
    return date('d-m-Y', strtotime("first $day of this month"));
}

Usage:

echo getDateFromDay('Monday');

Output:

02-09-2013
