If the file you are including is of your own authorage (I know that isn't a word, but whatever :), just refer to global variables always as an index of the $GLOBALS array. This is good practice anyways for any file that might be included by another user, for exactly this issue.
I have a file that could be a global include or not in my project, and making sure every global variable is referenced as $GLOBALS['varname'] fixed it for me without any fancy code (although Rasmus's code is very nice)

Is there anyway to include a file inside of a function and have the included stuff be global? For instance if I defined a class or a function in that include file, I want to be able to use that class outside of the function.
On the documentation for include() a poster commented that it did indeed work like this, but my testing indicates it does not. Everything stays local to the function and goes away when the function ends.
Is there a way?
Functions defined in included files are always global. So I guess it is just the variable you want to put out into the global symbol table. It's a little bit tricky, but you can do it like this:
function foo($filename) { extract($GLOBALS, EXTR_REFS); include $filename; $arr = array_diff(get_defined_vars(),$GLOBALS); foreach($arr as $var=>$val) $GLOBALS[$var] = $val; }
