Two functions to help: <?php function add_include_path ($path) { foreach (func_get_args() AS $path) { if (!file_exists($path) OR (file_exists($path) && filetype($path) !== 'dir')) { trigger_error("Include path '{$path}' not exists", E_USER_WARNING); continue; } $paths = explode(PATH_SEPARATOR, get_include_path()); if (array_search($path, $paths) === false) array_push($paths, $path); set_include_path(implode(PATH_SEPARATOR, $paths)); } } function remove_include_path ($path) { foreach (func_get_args() AS $path) { $paths = explode(PATH_SEPARATOR, get_include_path()); if (($k = array_search($path, $paths)) !== false) unset($paths[$k]); else continue; if (!count($paths)) { trigger_error("Include path '{$path}' can not be removed because it is the only", E_USER_NOTICE); continue; } set_include_path(implode(PATH_SEPARATOR, $paths)); } } ?>

In case you would like to have all include path elements in form of an array use the following code (PATH_SEPARATOR is PHP's constand and it's crucial to avoid problems with different linux/windows separators <?php $pathArray = explode( PATH_SEPARATOR, get_include_path() ); print_r( $pathArray ); ?>
