If you want to access a global variable in a function, it must be declared
"GLOBAL". Otherwise PHP's local scope would be totally useless.
If you want to access a variable inside of a function, you must explicitly
declare it as global.
There are a few exceptions such as $GLOBALS, but they should not be relied
on.
If nothing else, not using global in a function that requires a variable
that is declared outside of that function is bad practice.
Note: Try using get_defined_variables() inside of a function and see what it
returns.
