php - how to access $loader variable from within a class? -

app/config/routing.php

this how should done

$collection = new routecollection();  $collection->addcollection( // second argument type, required enable // annotation reader resource     $loader->import("@appbundle/controller/", "annotation") );  return $this->collection; 

i need create more complex routing system company, , need able register routes within class.

class autorouter extends appkernel {      function __construct()     {      }      public function registercontrollers()     {         $collection = new routecollection();         global $loader;         $collection->addcollection(             // second argument type, required enable             // annotation reader resource             $loader->import("@appbundle/controller/", "annotation")         );          return $this->collection;     }     //(....) } 

tldr; need access import function registercontrollers method, throws error

// answer      use symfony\component\routing\routecollection;      class autorouter extends appkernel     {         private $collection;          public function registercontrollers($loader)         {             $collection = new routecollection();             $collection->addcollection(                 // second argument type, required enable                 // annotation reader resource                 $loader->import("@appbundle/controller/", "annotation")             );              return $this->collection;         }          public function getactivebundles()         {             return $this->registerbundles();         }      }      $at = new autorouter('dev', true);     return $at->registercontrollers($loader); 

this perfect opportunity utilize dependency injection. should inject $loader instance type-hinted argument ensure correct object instance provided.

public function registercontrollers(loader $loader) { ... 

using dependency injection make easier change concrete implementation in future without changing 'consuming' code.

happy coding!
