// I noticed that there is already a built-in function that // Does the same-so don't use mine ;-) // // --> Shuffle ($ Array ); // // Http://de2.php.net/manual/de/function.shuffle.php // Function RandomizeArray ($ array ){ // Error check: $ Array = (! Is_array ($ array ))? Array ($ array): $ array; $ A = array (); $ Max = count ($ array) + 10; While (count ($ array)> 0 ){ $ E = array_shift ($ array ); $ R = rand (0, $ max ); // Find a empty key: While (isset ($ a [$ r]) { $ R = rand (0, $ max ); } $ A [$ r] = $ e; } Ksort ($ ); $ A = array_values ($ ); Return $; }
