[PHP "internal" access modifier]

There is also another scenario. Like this:

class base{
     public function setParam($key, $callable){
          $this->params[$key] = $callable;
     }
     internal function run(){
          foreach($this->params as $key=>$callable)
                 $callable();
     }
}
$base = new Base();
// if internal was possible, users will not be able to call this method outside this file. Especially usefull for frameworks and PHP applications.
$base->run();

If you know what I mean. And yes, PHP isn´t C#, but PHP hosting is cheaper than ASP.NET. So it is pity that internal does not exists in PHP.

i think you can use "final" for that...  

class base{

public function setParam($key, $callable){

$this->params[$key] = $callable;

}

final function run(){

foreach($this->params as $key=>$callable)

$callable();

}

}

 

If you use like this then you cannot modify this method in any derived classes..
