Best way to retrieve the current static function call

[vpxyz]

Hi, I'm try to figure out how to retrieve the current static function call. In code like this

   <?php
   UI\Control::enable(); 

if the cursor position is before ::, (thing-at-point 'sexp t) return UI\\Control, after the :: return enable.
There is in php-mode a function that returns the whole static method call?
