php - Get which day of the week the month starts on for given input

Question

I have a function which defines what day of the week the month starts on for the current month:

public function firstDayOfMonth()
    {
        $day =  (int) date("w", strtotime(date('m').'/01/'.date('Y').' 00:00:00'));
        return $day;
    }

How would I alter the above, in a way that allows me to get the day of the week the month starts on if I give it input, for example 'June'.

Answer 1

You can simplify your code to this:

$month = 'June';
$day = (int) date('w', strtotime($month));
