sorting some weird array in php by a value

Question

How can i sort something like this

$a = array(
        0  =>  array(
                 'field' => array( 
                            'id'=>'valueid'
                  )
        )
);

by valueid? I have managed to sort it by field but i can't realize how to do this weird sorting

This is the array Array ( [0] => Array ( [field] => Array ( [0] => Array ( [id] => value ) ) ) } – Mihai Dec 5 at 12:27
