[PHP] parent constructor
Hey guys just a general question... if you have a parent::__constructor() call in your constructor function, should that call ideally be placed before or after the code inside the current constructor? or it doesnt really matter -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Seriously. true in practice but in theory the parent ctor should be called first before anything else is done - the theory is that the 'base of the object' should be completely setup before you construct stuff in the current level (which may rely on stuff that is configured/setup in the parent ctor). so, what Jasper said, basically. NB: it's parent::__construct() not parent::__constructor() Jasper -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] parent:: constructor
Hi, Can anyone point me to a good explanation of how the parent:: constructor works? I've tried searching the php site for it with no success. I've been given a set of code to work on, but am getting the error: Fatal error: Undefined class name 'parent' for one section of it. cheers.

Um, you know the name of your parent class, so why do you use
get_parent_class() at all?

so that way I can have a general purpose way of calling a parent
constructor like "super()" or whatever. It seems silly to hardcode
the name of my parent class into the code of the class besides in the
"extends" part in the definition. that way if I change the
hierarchy, I don't have to worry about changing the constructor, it
just always points to the parent.
sorry if that isn't clear.

[PHP] parent constructor
why doesn't this work?
$parentClass = get_parent_class($this);
parent::{$parentClass}();
I get a parse error. can I not use variable functions with the "::" syntax?
I tried eval() and it loses the context.
thanks for the help!
