Therefore I request the introduction of a new function (for the sake of the discussion, I'll call it "array_change_keys") that takes an array and a callback and then calls the callback for each key, passing the key as a parameter (possibly also passing the value as another parameter) and replaces the old key with the return value of the function call - under the same constraints as mentioned in http://php.net/array_change_key_case in terms of replacing elements with colliding keys. Signature: array array_change_keys ( array $input, callback $callback ) Reproduce code: --------------- <?php $a = array( 'peter' => 'm, 71', 'paul' => 'm, 72', 'mary' => 'f, 73' ); $b = array_change_keys($a, 'strlen'); Expected result: ---------------- $b === array( 5 => 'm, 71', 4 => 'f, 73' ) ('paul' was overridden by the element 'mary' which resulted in the same key name) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=48543&edit=1
