mit print_r kommt unten das raus

[85] =>
[86] =>
[87] =>
[88] =>
[89] =>
[90] =>
[91] =>
[92] =>
[93] =>
[94] =>
[95] =>
[96] =>
[97] =>
[98] =>
[99] =>
[100] =>
[101] =>
[102] =>

okay, geh ich mit dieser funktion hin

PHP-Code:

function unsetEmpty($array){
    if(!is_array($array)) return -1;
    else{
        for($i = 0; $i<count($array); $i++){
        
           if($array[$i] == ''){unset($array[$i]);}
           
          }
        return $array;
    }
} 


na dann ist das immer noch da?
what the hell?

habe auch if strlen kleiner 1, auch pord versucht

das geht zum kotzen nicht weg

bitte hilfe

danke euch!

Und wie wäre es mit array_filter() ohne Angabe eines Callbacks

danke dir
woran lag mein fehlr jetzt?

Keine Ahnung....
Der kompliziertere Weg interessiert mich meist nicht so sehr.

Nur weil nichts ausgedruckt wird, heisst das noch lange nicht, dass es sich um einen leeren String ("") handelt
