How can i configure it via php.ini or iis or else?

I think you just need to chdir() in your script:

chdir(__DIR__);

Or, before PHP 5.3:

chdir(dirname(__FILE__));

To the currently executed script directory: chdir(dirname($_SERVER['SCRIPT_FILENAME']));

To the currently executed file directory: chdir(dirname(__FILE__));

There is a slight difference between them. Script directory is always the directory of the main script file being executed, while the file directory can also be the directory of the included php script file.
