How to access and manipulate multi-dimensional array by key names / path?

Question

I\'ve to implement a setter in PHP, that allows me to specify the key, or sub key, of an array (the target), passing the name as a dot-separated-keys value.

Answer 1

Here a simple code to access and manipulate MD array. But there's no securities.

setter :

eval('$vars = &$array["' . implode('"]["', explode('.', strtolower($dot_seperator_path))) . '"];');
$vars = $new_value;

getter:

eval('$vars = $array["' . implode('"]["', explode('.', strtolower($dot_seperator_path))) . '"];');
return $vars;
