set_include_path — Sets the include_path configuration option
Sets the include_path configuration option for the duration of the script.

success або false в разі помилки.
Приклад #1 set_include_path() example
<?php
set_include_path('/usr/lib/pear');
// Or using ini_set()
ini_set('include_path', '/usr/lib/pear');
?>
Приклад #2 Adding to the include path
Making use of the PATH_SEPARATOR constant, it is
possible to extend the include path regardless of the operating system.
In this example we add /usr/lib/pear to the end of
the existing include_path.
<?php
$path = '/usr/lib/pear';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);
?>
If you find that this function is failing for you, and you're not sure why, you may have set your php include path in your sites's conf file in Apache (this may be true of .htaccess as well)
So to get it to work, comment out any "php_value include_path" type lines in your Apache conf file, and you should be able to set it now in your php code.
