Difference Bettween Include(),Include_once() and Require() in PHP

Include () will include the file specified.
Include_once () will include the file only once even if the code of the file has been included before.
Require () and include () are the same with respect to handling failures. However, require () results in a fatal error and does not allow the processing of the page.
