This complete code of function

[php]
function shuffle_arraykeys(array $arraydata()){
foreach($arraydata as $num_key=>$num_val){
$array_keys[$num_key] =$num_key;
}
while(true){
$array_randkey = array_rand($array_keys);
$val = $numbers[$array_randkey];
if($val!==null){
$shuffeled_keys[$array_randkey] = $numbers[$array_randkey];
unset($numbers[$array_randkey]);
}
