Zend Studio (debug feature) 5.5 and XAMPP

I've install XAMPP for php,mysql. I use Zend Studio for writing
php,mysql

codes. I know Zend Studio 5.5 has debug feature for php codes. How can
i use

the debug feature of zend studio with XAMPP server. I tried to use
debug

feature but it say "could not conecct to http://localhost/dummy.php..
Do i have to change some setting in php.ini.

Please help me to activate the debug feature of the zend studio so that
i

can preview the code at realtime.

Best Regards,
