Re: global sessions

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. -- Plutarck Should be working on something... ...but forgot what it was.
