php - What is the point of nulling private variables in destructor? -

-

i have spot following pattern in code i'm working with: in classes in destructor have found private variable being nulled, in example:

public function __destruct() {     foreach($this->observers $observer)     {         $observer = null;     }     $this->db_build = null; }

is there point in doing when php has gc? somehow improve performance of script?

it could because php's garbage collection based on reference countring, , older versions not handle cyclical dependencies. then, in cases have been necessary manually set references null enable gc work, , there may still special cases cycle detection algorithm not catch.

more though, it's example of cargo cult programming (the wikipedia entry explicitly lists example).
