Triggering a function when a parent public method is called (like __call)

Question

A word before my question to say I am pretty new to OOP in PHP, and I'm very grateful to the site, and you all for reading - and sometimes answering beautifully (as you can see here or here , or even here ) and helping big time my late (sort of) improvement dealing with classes.

All my previous questions lead me today to this one:
In a class extending PDOStatement, how can I trigger a default action each time one of the parent public methods is called?

I can do this:

class genc_query extends PDOStatement{
  public function rowCount(){
    $this->myDefaultAction();
    return parent::rowCount();
  }
}

But as I need to change in the same way almost all of the native methods, I wonder if there's no way to trigger a function like __call() as if these methods were private (as it's not possible to make them private).

Answer 1

as it's not possible to make them private

Indeed, this seems to be the case.

ReflectionMethod can let you change the accessibility of a method , but it seems that it either doesn't work on internal methods (ie not user-defined) or it won't set public methods to protected/private. It seems designed to make protected/private methods public instead.

It looks like your copy-and-paste boilerplate inside each method is going to be necessary. Besides __sleep and __wakeup , there are only about three dozen methods, so it should only take you a few minutes.

Answer 2

For the sake of clear code, extend every method (means: overwrite and call parent::method() there), that you wants to have additional behaviour. Else there will be some day, where you or someone else may get really confused on what happens there.
