Use of require in PHP Library

ayz

Within the code of PHP library, I see usage of require as opposed to require_once. Just curious as to why there was no performance concern in doing this from your end.

I was confident enough that in the libraries each script was only included once, so we didn't need the (albeit minor) overhead of require_once (since it needs to look up what was loaded before).

If you feel happier with it, you could certainly switch it to use require_once.
