How many times can you define _______ autoload in a process?

Answer & Solution
Correct Answer: Option A
__autoload is a powerful tool, but it does have some limitations. In particular, you can only define it once in a process. If you need to change your autoload function dynamically you should look at the spl_autoload_register function, which supports that functionality.
