include();--> include the file, but in case of file missing
throws a warning and continues execution of code of next line.
require();--> require also includes the file but in case of
file missing throws an fatal error and stop the execution of
the code of next line.
include_once();-->if same file was included first it will
not include the file another time.

Answer / ashwini
All three include(),include_once() and require() are used to
an include file into the current page.
If the file is not present, require(), calls a fatal error,
while in include() does not.
The include_once() statement includes and evaluates the
specified file during the execution of the script. This is a
behavior similar to the include() statement, with the only
difference being that if the code from a file has already
been included, it will not be included again. It does not
call a fatal error if file not exists. require_once() does
the same as include_once(), but it calls a fatal error if
file not exists.
