PHP Deep Extend Array

Question

How can I do a deep extension of a multi dimensional associative array (for use with decoded JSON objects). I need the php equivalent of jQuery\'s $.extend(true, array1, arr

Answer 1

With a little googling I found this:

/**
 * jquery style extend, merges arrays (without errors if the passed values are not arrays)
 *
 * @return array $extended
 **/
function extend() {
    $args = func_get_args();
    $extended = array();
    if(is_array($args) && count($args)) {
        foreach($args as $array) {
            if(is_array($array)) {
                $extended = array_merge($extended, $array);
            }
        }
    }
    return $extended;
}

extend($defaults, $new_options);
