PHP's array_map including keys

Question

Is there a way of doing something like this:

$test_array = array(\"first_key\" => \"first_value\", 
                    \"second_key\" => \"second_valu

YaLinqo library* is well suited for this sort of task. It's a port of LINQ from .NET which fully supports values and keys in all callbacks and resembles SQL. For example:

$mapped_array = from($test_array)
    ->select(function ($v, $k) { return "$k loves $v"; })
    ->toArray();

or just:

$mapped_iterator = from($test_array)->select('"$k loves $v"');

Here, '"$k loves $v"' is a shortcut for full closure syntax which this library supports. toArray() in the end is optional. The method chain returns an iterator, so if the result just needs to be iterated over using foreach, toArray call can be removed.
