It's been a week since I submitted this, and it's still not assigned to
anyone. Do I need to include more information?

Description:
------------
While working recently on a project that involves JSON, I saw that it
might be necessary to make sure that a an array's keys are in utf-8
encoding for when I pass it to the JSON encoder, since JSON expects
stuff to be in utf-8. One possible way to do this with PHP's existing
array functions is with array_combine(), and converting all the
elements in the keys array to utf-8 before combining it with the
elements array, but this seems like it could become more tedious with
nested arrays. I tried using foreach($array as &$key => $val) to
convert the key's encoding in each iteration, but got an error saying
"Fatal error: Key element cannot be a reference". So I wrote my own
function (included below).
Why isn't there an array_key_walk_recursive() function, or something of
the kind? A function that would let you apply a callback to all keys in
an array. Or, let you use foreach with a referenced key as I mentioned.
Reproduce code:
---------------
<?php
function array_convert_key_encoding($array) {
$encoded_array = array();
foreach($array as $key => $val) {
if(is_string($key) && is_array($val)) {
$encoded_array[utf8_encode($key)] =
array_convert_key_encoding($val);
}
else if(is_string($key)) {
$encoded_array[utf8_encode($key)] = $val;
}
else {
$encoded_array[$key] = $val;
}
}
return $encoded_array;
}
?>
