Get date for monday and friday for the current week (PHP)

Best solution would be:

$monday = date( 'Y-m-d', strtotime( 'monday this week' ) );
$friday = date( 'Y-m-d', strtotime( 'friday this week' ) );

These strtotime inputs work very well:

strtotime( "next monday" );
strtotime( "previous monday" );
strtotime( "today" );
strtotime( "next friday" );
strtotime( "previous friday" );

All you need to do is to wrap the logic inside some if statements.

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)

See it working

i use :

$first_week_date = date('d F Y', strtotime('next Monday -1 week', strtotime('this sunday')));
$last_week_date = date('d F Y', strtotime('next Monday -1 week + 4 days', strtotime('this sunday')));
