onExtensionFunction uses the super-global variable $GLOBALS which is generally not recommended.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Instead of super-globals, we recommend to explicitly inject the dependencies
of your class. This makes your code less dependent on global state and it
becomes generally more testable:


// Bad
class Router
{
    public function generate($path)
    {
        return $_SERVER['HOST'].$path;
    }
}

// Better
class Router
{
    private $host;

    public function __construct($host)
    {
        $this->host = $host;
    }

    public function generate($path)
    {
        return $this->host.$path;
    }
}

class Controller
{
    public function myAction(Request $request)
    {
        // Instead of
        $page = isset($_GET['page']) ? intval($_GET['page']) : 1;

        // Better (assuming you use the Symfony2 request)
        $page = $request->query->get('page', 1);
    }
}

The method onExtensionFunction() contains an exit expression.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
An exit expression should only be used in rare cases. For example, if you
write a short command line script.


In most cases however, using an exit expression makes the code untestable
and often causes incompatibilities with other libraries. Thus, unless you are
absolutely sure it is required here, we recommend to refactor your code to
avoid its usage.
