Is there a way to make an array global?
I load it in one function and need to use it in several other functions.
Thanks!

Each function will need to define it as global. This is very poor programming practice. I'd encourage you to find another solution.
Code: Select all
function foo() {
global $myArray;
}

Well, for some reason it is empty.
I know it has data in it at the end of a function because I dump it.
When I execute the next function, I try to dump it immediately but it display "null".
Any other suggestions?

Nope. That's how you do it.

Do I need to include the array names in the function's variables list?
Do I need to include
global $myarray;
in each of the functions?

you also have to declare it global in the beginning, *before* declaring it global again in each function, and yes, in each and every function you wish to have access to it.
