Get Start and End Days for a Given Week in PHP

Question

I\'m trying to get the week range using Sunday as the start date, and a reference date, say $date, but I just can\'t seem to figure it out.

For example,

Answer 1

Base on @jjwdesign's answer, I developed a function that can calculate the beginning and ending of a week for a specific date using the DateTime class. WILL WORK ON PHP 5.3.0++

The difference is you can set the day you want as the "beginning" between 0 (monday) and 6 (sunday).

Here's the function :

if(function_exists('grk_Week_Range') === FALSE){
    function grk_Week_Range($DateString, $FirstDay=6){
        #   Valeur par défaut si vide
        if(empty($DateString) === TRUE){
            $DateString = date('Y-m-d');
        }

        #   On va aller chercher le premier jour de la semaine qu'on veut
        $Days = array(
            0 => 'monday',
            1 => 'tuesday',
            2 => 'wednesday',
            3 => 'thursday',
            4 => 'friday',
            5 => 'saturday',
            6 => 'sunday'
        );

        #   On va définir pour de bon le premier jour de la semaine     
        $DT_Min = new DateTime('last '.(isset($Days[$FirstDay]) === TRUE ? $Days[$FirstDay] : $Days[6]).' '.$DateString);
        $DT_Max = clone($DT_Min);

        #   On renvoie les données
        return array(
            $DT_Min->format('Y-m-d'),
            $DT_Max->modify('+6 days')->format('Y-m-d')
        );
    }
}

Results :

print_r(grk_Week_Range('2013-08-11 16:45:32', 0));
print_r(grk_Week_Range('2013-08-11 16:45:32', 1));
print_r(grk_Week_Range('2013-08-11 16:45:32', 2));
print_r(grk_Week_Range('2013-08-11 16:45:32', 3));
print_r(grk_Week_Range('2013-08-11 16:45:32', 4));
print_r(grk_Week_Range('2013-08-11 16:45:32', 5));
print_r(grk_Week_Range('2013-08-11 16:45:32', 6));
