    I believe the difference is that include generates an error message if it can't find the file and require generates a fatal error and stops script execution.

    That's right:

    - include() includes a file in memory no matter if it has already been loaded
    - include_once() includes a file in memory only if it has not been loaded already
    - require() includes a file in memory no matter if it has already been loaded. if the file cannot be loaded, the script is aborted
    - require_once() does the same as require(), but only if the file hasn't been included yet. if the file's already in memory, it has no effect.

    ...and if the file was already included, both this functions return TRUE
