Question

This might be a very noob question, but I can’t seem to find the answer anywhere. Is it possible to make your own function in a component and call it in the same component?

Example:

Class myComponent extends Component{

 public function doSomething(){

  doThis();

  $b = $a + 2;

  return $b;

 }

 function doThis(){

  $a = 0;

 }

}

You are mixing up several things here.

1. You can generally create object methods like this without problem. You have to call them as objects methods though:

   public function doSomething() {
       $this->doThis();
       ...
   }
   

2. Just calling doThis() won’t magically create the variable $a in the calling scope. The variable will be created inside doThis and will be contained there. And that’s a good thing. You’ll have to explicitly return the value from the method to make it available:

   public function doSomething() {
       $a = $this->doThis();
       ...
   }
   
   protected function doThis() {
       return 0;
   }
