Description:
------------
Hi!
Either its some documentation problem or a error reporting problem, but "static" and "global" can be used in the global scope, and this makes no sense?
Or is it some kind of: make statics or globalize variables in a file included in a function in another file? if so, close this bugreport and eventually make some documentation for that... :)
thx and greets

Reproduce code:
---------------
<?php
error_reporting(E_ALL);

# The php doc says "A static variable exists only in a local function scope"
# but this does not fail in any way:

static $test = 1;
echo("test for static successfull\n");

# As global does only makes sense within the function, this should fail
# also with some error or something:

global $test2;
echo("test2 for global successfull\n");


Expected result:
----------------
Any error message like "The keyword static|global is not allowed in global scope"

Actual result:
--------------
test for static successfull
test2 for global successfull

global scope != at the main scope of your file. Remember that a file could be included in a function's scope. But sure, it doesn't make much sense to have those in the real global scope, not sure it's worth a runtime notice/warning though
