Use array_filter() and a callable to fit your needs (here an anonymous fonction) :

$searchedValue = 'license_number';
$o = array_filter( $items,
    function ($e) use (&$searchedValue) {
        return $e->meta_key == $searchedValue;
    }
);

Note the return is an array of objects containing all values that fit the condition. This will give you the first result.

reset($o);
