Q: 

what are the main differences between require, require_once, include and include_once in PHP

Hi, what are the main differences between require, require_once, include and include_once in PHP

+1  A: 

include and include_once will accept missing scripts without throwing an error.

The _once ending ensures that the particular script is only run once for a single http request.
