Hi!

A good idea, which I have used for some classes, like the Journal 
class  (error handling) which fits in with the Core class. 
Unfortunantly I have  too many classes to make them all into a chain 
of child classes. And  also I have an ambition to write these classes 
in sorta seperate tools,  which I can then use in other projects with 
no altering of the code.

The database (mysql) class is such a class, which is in use in almost  
every project I work at.

Would it be possible to create a member variable to a class on the 
fly,  without specifically creating it when you write the class? 
Something  like this:

<?php
class MyClass {
     var $MemberVar1 = "";
     var $MemberVar1 = "";

function MyClass() {
     //constructor
}
function MkMemVar($newmemvar, $memvarval) {
     $this->newmemvar = $memvarval;
     // this is just an example, don't know it would actually be done so
     // but you get the idea: the $newmemvar would be the name of the new
     // member variable and $memvarval would be the value for the new
     // member variable.
}
?>

possible.

Or could it even be possible to do this outside of a class? So that I  
yes, that is possible.

wouldn't have to specify a seperate function for it in my classes?

This way I could make an instance of another class inside any class 
on  the need-bases and it would solve my problem. Is there anyway to  
accomplish this? I couldn't find any immediately solution by looking 
at  the php manual, but it doesn't mean it's not there.
