I have a main class and other sub classes that are extensions of the main class. I want to have a variable in the main class that can be affected by the sub classes... I'll try to explain better. $main = new MAIN; // main class $sub = new SUB;// sub class 1 extension of main $sub2 = new SUB2; //sub class 2 extension of main $sub->testvar++; echo $sub->testvar; //test var is located in the main class // will output 1 $sub2->testvar++; echo $sub2>testvar; //wil output 1 What I want the program to do is realise that testvar has been changed by sub and i want sub2 to output 2 and not 1. I'm not sure how to implement this into classes, I realise that sub and sub2 both have same structure of main but completly different memory addresses. So how can I fix this?
