I want to convert weekdays with a simple function like $wdays = array

    (0 => "Sonntag"
    ,1 => "Montag"
    ,2 => "Dienstag"
    ,3 => "Mittwoch"
    ,4 => "Donnerstag"
    ,5 => "Freitag"
    ,6 => "Samstag"

); function convert_from_weekday ($weekday) {

    return $wdays[$weekday];

} but this doesn't work while $wdays[$weekday]; outside of the function works correct. Has anybody an idea where's my mistake? I'd like to use a function so I may return substrings of the weekday. O. Wyss

$wdays is not defined inside the function, so you can do a few things: - Pass the $wdays inside the function: function convert_from_weekday ($weekday,$wdays) { return $wdays[$weekday]; } $day = convert_from_weekday(0,$wdays) // $day = "Sonntag" - You could define $wdays inside the function function convert_from_weekday ($weekday,$wdays) { $wdays = array (0 => "Sonntag" ,1 => "Montag" ,2 => "Dienstag" ,3 => "Mittwoch" ,4 => "Donnerstag" ,5 => "Freitag" ,6 => "Samstag" ); return $wdays[$weekday]; } $day = convert_from_weekday(0) // $day = "Sonntag" - If you are working from inside a class, you could define $wdays as a public variable. I think this solved your problem, but don't hesitate to ask for more! Tijnema
