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

You could use array_combine. It merges an array for keys and another for values...

For instance:

$original_array =('foo'=>'bar','asdf'=>'fdsa');
$new_keys       = array('abc', 'def');
$new_array      = array_combine($new_keys, $original_array);
