zend studio9+xdebug配置ok，依然调试不了

按照http://xdebug.org/find-binary.php的配置方式。输出如下信息：

Tailored Installation Instructions

Summary

Xdebug installed: 2.1.2
Server API: Apache 2.0 Handler
Windows: yes - Compiler: MS VC9 - Architecture: x86
Zend Server: no
PHP Version: 5.3.8
Zend API nr: 220090626
PHP API nr: 20090626
Debug Build: no
Thread Safe Build: yes
Configuration File Path: C:\Windows
Configuration File: D:\studySoft\PHP\php.ini
Extensions directory: D:\studySoft\PHP\ext
You're already running the latest Xdebug version

But here are the instructions anyway:

Download php_xdebug-2.1.2-5.3-vc9.dll
Move the downloaded file to D:\studySoft\PHP\ext
Update D:\studySoft\PHP\php.ini and change the line
zend_extension = D:\studySoft\PHP\ext\php_xdebug-2.1.2-5.3-vc9.dll
Restart the webserver

成功配置了。zend studio的debug模式也选择的是xdebug。但是依然无法调试。
php.ini有关xdebug配置：

实在不知道哪里出了错，各位，帮忙看下哦！谢谢啦

没有弄过这个，向来调试都是不断的print_r,die()
