What are autoglobals?

Autoglobals are things that are registered automatically by PHP as global variables - and hence they are known as 'auto' in reference to the first bit and 'global' in reference to the second.

For instance if you send data through a form using the POST method, you will automatically have $_POST made available which is an autoglobal array containing all the keys and values passed through that form through the POST method.

There are several other global variables set this way.
