What is difference between require_once (), require(), include()?

require() includes and evaluates a specific file, if file isn't found then it shows a Fatal Error.

require_once() includes only the file which isn't being included before. It's used to be recommended for the files where you have lots of functions stored.

include() includes the file, even if file isn't found however it gives a warning to the user to include().
