I could be wrong, but IMHO the best way to perform array_map recursively AND preserve keys would be
this:
<?php
# Apply a callback to an array and preserve keys, even if that array is multidimensional
function x_array_map($callback, $array)
{
foreach($array as $k => $v)
if(is_array($v))
$array[$k] = x_array_map($callback, $v);
else
$array[$k] = call_user_func($callback, $v);
return $array;
}
?>
