How many times can you define _______ autoload in a process?
A
once
B
twice
C
thrice
D
as many times as needed
Correct Answer: once
__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.
