始终被调用的PHP方法

Question

I'm currently working on an own PHP-MVC-Framework (for experience purposes only).

My question: Is it possible to call a defined function or method, every time a class-method has been called?

For example:

public function view($id) {
     //Code ...
     $this->view->render(__FUNCTION__);
}

What I want is:

public function view($id) {
    //Code ...
    //render-method is called automatically with functionname as parameter
}

I tried different methods ... but without success. Would be great if someone could help me out with this.

Cheers, Chris

Answer 1

You can use Magic Methods do achieve this behavior:

public function __call($func, $args) {
  if(!method_exists($this, $func)) {
    return;
  }

  // do some coding here
  call_user_func_array($func,$args);
  // do some coding there
}

private function view($arg1, $arg2) {
  // and here
}

Remember: view function must be private/protected.

$obj->view("asdasd", "asdsad");

Should do ::__call(), then ::view() method

Answer 2

You could create a function as a liaison using PHP's ability to use variable values for execution purposes. for example:

function call($func,$param)
{
    $this->$func($param);
    $this->render($func);
}

$myObj->call('view',$id);

You can use a wrapper method. Call this method and pass everything else as a parameters.
