Taken directly from the manual.

http://us.php.net/manual/en/function.include.php

Please note that include(), include_once(), require(), and
require_once() all function the same so far as in reference to your
question.

" Files for including are first looked in include_path relative to the
current working directory and then in the directory of the current
script. E.g. if your include_path is libraries, current working
directory is /www/, you included include/a.php and there is include
"b.php" in that file, b.php is first looked in /www/libraries/ and
then in /www/include/. If filename begins with ./ or ../, it is looked
only in include_path relative to the current working directory.

When a file is included, the code it contains inherits the variable
scope of the line on which the include occurs. Any variables available
at that line in the calling file will be available within the called
file, from that point forward. However, all functions and classes
defined in the included file have the global scope. "
