• How to implement callback functions inside classes (PHP)

  - by sombe

  I need to use a class callback method on an array inside another method (the callback function belongs to the class). class Database { public function escape_string_for_db($string){ return mysql_real_escape_string($string); } public function escape_all_array($array){ return array_filter($array,"$this->escape_string_for_db"); } } Is this the right way to go about that? (I mean, in terms of the second parameter passed to array_filter)

• Java reference storage question

  - by aab

  In java, when you pass an object to a method as a parameter, it is actually passing a reference, or a pointer, to that object because objects in Java are references.

Is a new memory location created once inside the function to hold this reference?

• Function callers in C?

  - by thyrgle

  So I was wondering how they work. To explain what I mean by a "function caller" a good example of what I mean would be glutTimerFunc, it is able to take in a function as a parameter and call it even with it not knowing it is declared. How is it doing this?

• Finding the type of an object in C++
