How to intercept calls to the variable?

[MorrisonHotel]

class Test {
  public $var1 = 0;
 
  private function simple() {
    // smth
  }
}
 
$obj = new Test;
$obj->var1 = 1;
 

I want a change of variable var1 immediately fulfilled the function simple. How to do it?

That is not possible to do. You can't have a listener or trigger in a class (Disclaimer: that I know of with basic implementation of OOP).

You can just use a Setter method and call that instead of changing the variable.

 
public function setVar($newVal)
{
   $this->var1 = $newVal; 
   $this->simple(); 
}
 
}// end class
 
$obj = new Test; 
$obj->setVar(1); 
 
 

You should try to have accessors and setters for all your members. Google Encapsulation.
