Change array key without changing order

Question

You can \"change\" the key of an array element simply by setting the new key and removing the old:

$array[$newKey] = $array[$oldKey];
unset($array[$oldKey]);         


        

Answer 1

Do a double flip! At least that is all I can think of:

$array=("foo"=>"bar","asdf"=>"fdsa");
$array=array_flip($array);
$array["bar"]=>'newkey';
$array=array_flip($array);
