Call to %s method %s::%s() from %s%s

Description

A private method shall only be called from within its own class. It cannot be called from another class, or from the global space. In particular, the method cannot be called directly, or indirectly: for example, new X indirectly calls the __construct method.

A public method may be called from anywhere in the code.

class X {
    //This is also the case with proctected __construct
    private function __construct() {}

    static public function factory() {
        return new X();
    }
}

//This is not possible
$x = new X();

?>
