Do I need to include more information? ------------------------------------------------------------------------ [2006-09-01 20:45:17] z_rules55 at hotmail dot com 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; } ?> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=38684&edit=1
