OOP return this question

[razorsese]

I have the following code:

 

 

My question is how i can return both the y and the z in magic function.( works with y alone)

 

class X{
  private y;
  private z;


   public function __construct($y,$z) {
    $this->y = $y;
    $this->z = $z;

   }
  public function magic()
  {
    return $this->{ $this->y }(); //need to return both  Y & Z
  }
}

[iarp]

return array($this->y, $this->z);

 

list($myOwnVarForY, $myOwnVarForZ) = $X->magic();

By the way,

return $this->{ $this->y }();

is quite wrong. Even if it's syntactically valid (might be) it won't do what you want it to do.

Yep.

 

return $this->{ $this->y }();

Actually return the function with name Y.

Just checked, it is valid.

Actually return the function with name Y.

Call the function named whatever the value of $this->y is.

call_user_func(array($this, $this->y));
