Just another thought... If you are calling this function a ridiculous number of times, you could use a static variable. function convert_from_weekday($weekday){ static $weeks = ''; if ($weeks === '') $weeks = array('Sonntag', 'Montag', ...); } It's kind of a shame that PHP won't let you just initialize a static to an array, but there it is. -- Some people have a "gift" link here.
