Answer 1

If you read the manual, there is an great example that describes exactly what you want to do http://www.php.net/manual/en/datetime.formats.relative.php

strtotime('Monday this week');

Update: There appears to be a bug introduced in newer versions of PHP where this week returns the wrong week when ran on Sundays. You can vote on the bug here: https://bugs.php.net/bug.php?id=63740

Update 2: As of May 18th 2016, this has been fixed in PHP 5.6.22, PHP 7.0.7 and PHP 7.1-dev (and hopefully remains fixed in subsequent releases) as seen here: https://bugs.php.net/bug.php?id=63740#1463570467

Answer 2

My aproach:

date_default_timezone_set('Europe/Berlin');
function givedate($weekday, $time) {
$now = time();
$last = strtotime("$weekday this week $time");
$next = strtotime("next $weekday $time");
    if($now > $last) {
        $date = date("d.m.Y - H:i",$next);
    }
    else {
        $date = date("d.m.Y - H:i",$last);
    }
    return $date;
}

echo givedate('Wednesday', '00:52');

Or monthly

    function givedate_monthly($weekday, $time) {
    $now = time();
    $last = strtotime("first $weekday of this month $time");
    $next = strtotime("first $weekday of next month $time");
        if($now > $last) {
            $date = date("d.m.Y - H:i",$next);
        }
        else {
            $date = date("d.m.Y - H:i",$last);
        }
        return $date;
}

echo givedate_monthly('Wednesday', '01:50');
