Question

Is there a way to declare a variable so it is available in all functions. Basically I want to call: Global $varName; automatically for every function. And no, I can t use a constant.

I don t think its possible but wanted to ask anyway. Thanks! :D

Answer 1

That s pretty oldschool and not recommended. If you want to use variables whereever you want consider using sessions of passing through variables if you re on an object oriented tour ;)

Answer 2

There is a $GLOBALS variable and a globals keyword.Check out example 1 and 2 on this page in the documentation.

But using a global variable is usually a sign of bad structure in your code.

Answer 3

I don t think variables can be globally visible the way you want bnut functions are.

You can declare two functions to access you data : on for reading, one for writing.

But anyway beware : if you change it from many places you will have hard times understanding what s going on when faced with a bug !
