hi, i found your tutorial regarding difference between include() vs include_once() now i want to ask you a questions, can you please explain a little bit about the differences between require and require_once in php

from what i have read in the php.net website, im thinking they are same same as include()

The include() statement includes and evaluates the specified file. - The documentation below also applies to require().

of basically, there is not difference, unless anyone knows any specific differences. please tell me
