Out-of-the-box Eclipse PDT (PHP Development Tool) not capable of debugging PHP, why?

I just finished reinstalling the "All-In-One Eclipse PDT" from zend.com. It's unable to debug even the simplest "Hello World" PHP script. How can such a major open-source app be released in such a bad shape? What am I doing wrong?

Th开发者_运维百科is is the result of doing a "Debug As... 2. PHP Script":

I think it wants me to configure some additional stuff, but I have no clue what exactly to do.

Did you check your PHP installation as in this thread?

After uninstalling XAMPP and reinstalling it (xampp-win32-1.7.0-installer.exe) and applying the xampp-patch2-win32-1.7.0-installer, I still have the problem of the PHP CLI closing and throwing the pop-up dialog.

OK, you must also copy "php_mysql_5.0.51a.dll" to "php_mysql.dll" and "php_mysqli_5.0.51a.dll" to "php_mysqli.dll" in "\xampp\php\ext".
