PHP include path error -

i keep getting error when try include simpletest in include_path:

<? set_include_path(get_include_path() . path_separator . realpath(basename(dirname(__file__)) . '/../../'));  include 'simpletest/autorun.php'; 

returns:

.:/usr/lib/php:/users/kristiannissen/documents/php warning: require_once(/users/kristiannissen/documents/php/simpletest/arguments.php): failed open stream: no such file or directory in /users/kristiannissen/documents/php/simpletest/reporter.php on line 13  fatal error: require_once(): failed opening required '/users/kristiannissen/documents/php/simpletest/arguments.php' (include_path='.:/usr/lib/php:/users/kristiannissen/documents/php') in /users/kristiannissen/documents/php/simpletest/reporter.php on line 13 

personally view pages first executed, such index.php , view pages should in root of html.

so within index.php can do:

define("base_path",str_replace("\\","/",dirname(__file__))); 

so base_path equal to: /users/kristiannissen/documents/php/simpletest

so if want phpdirectory in include path should use dirname() go up directory:

//get array of include paths $include_parts = explode(path_separator,get_include_path());  //extend paths $include_parts[] = dirname(dirname(base_path)); //this ../../  //recompile paths , set them set_include_path(implode(path_separator,$include_parts)); 

this safe way accomplish trying do.
