Question

I have a class

class SomeClass {
  private $someVar;

  public function Init($func) {
    $this->someVar = $func;
  }

  public function DoSomething() {
    $this->someVar("asdasdasd");
  }
}

$obj = new SomeClass();
$obj->Init(function ($param){var_dump($param);});
$obj->DoSomething();

When I call the method DoSomething, I get an error that SomeClass::someVar() is undefined method. But when I use the debugger, I see that it is a closure object. If I save the function into a local variable ($someVar without $this) and call it in the Init() function, it works just fine. But I don’t want to call the function there. I want to call it later.

Even if I save it into $this->someVar and call it in the same scope it does not work.

Maybe you should simply try this :

public function DoSomething()
{
  $tmpVar = $this->someVar;
  $tmpVar("asdasdasd");
}

or, if you prefer, this :

public function DoSomething()
{
  call_user_func($this->someVar, "asdasdasd");
}
