Answer 1

This question needs a DateTime answer:-

/**
 * @param String $day
 * @return DateTime
 */
function getDay($day)
{
    $days = ['Monday' => 1, 'Tuesday' => 2, 'Wednesday' => 3, 'Thursday' => 4, 'Friday' => 5, 'Saturday' => 6, 'Sunday' => 7];

    $today = new \DateTime();
    $today->setISODate((int)$today->format('o'), (int)$today->format('W'), $days[ucfirst($day)]);
    return $today;
}

Usage:

var_dump(getDay('Monday')->format('l dS F Y'));
var_dump(getDay('Friday')->format('l dS F Y'));

Output:

string 'Monday 30th September 2013' (length=26)
string 'Friday 04th October 2013' (length=24)
