That doesn't really answer Jerry's question in the context of PHP.
BTW assuming you mean globals applying to the whole website (or application
if you prefer) you can use autoprepend to reference the file instead of
explicitly including it - but you loose a lot of transparency and
flexibility.
BUT YOU ARE NOW WRITING IN PHP. Don't load code you don't need. If you use
the autoloader PHP will find the files and load them.

You seem to be digging yourself a hole here.
The right solution is to understand how the include_path works and set it up
for your requirements.
