2D array variable scope

[Anon]

Hi,

pretty complicated but here goes, my problem is that I can't unset $items in the while loop. script 1 works fine. script 2 always adds to the array but only in the function
I dont know if i am being clear, but I cant seem to affect the $GLOBALS[] value of $items
but I cant do $GLOBALS[item[]] ....

script 1
GLOBAL $items
$items[] = array(1,2,3);
a();

script 2
GLOBAL $items
while(condition)
{
$items[] = array(1,2,3);
a();
//I need to unset items here
}

function a()
{
GLOBAL $items
case 1 b();
case 2 c();
//depending on option calls different functions
}
function b()
{
manipiulate $items
}
function c()
{
manipiulate $items
}

Rule #1, never use globals.

If you need to use a variable in a function, then give that variable to the function as a parameter. Forget globals, they are evil.

True. In your situation you should pass the array to your a() function.

There are situations where you should use globals, though. Like in when you instantiate several nested class objects.
