PHP cannot configure xdebug?

PHP cannot configure xdebug? I have installed EPP3 and PHP5.4.5. if I want to configure xdebug for debugging, I cannot test xdebug by using phpinfo. I feel that PHP itself is not difficult. these development environments are sometimes difficult to configure. My configuration is as follows:
; Onload Xdebug
Zend_extension_ts = "C:/php5/ext/php_xdebug-2.2.1-5.4.dll"
; Xdebug configuration

[Xdebug]

Xdebug. auto_trace = On

Xdebug. show_exception_trace = On

Xdebug. remote_autostart = On

Xdebug. remote_enable = On

Xdebug. collect_vars = On

Xdebug. collect_return = On

Xdebug. collect_params = On

I have the same problem !!

I have such a problem !!!!

I also met, but I solved it. I wrote a general online tutorial. Although xdebug can be displayed on phpinfo, EPP can also start the perspective of xdebug. However, during EPP debugging, you cannot click next to perform one-step debugging. It is still under study.

My approach, refer to the tutorial http://blog.csdn.net/zuike/article/details/6095341, this tutorial written wrong place, is not to write xdebug. where to copy the dll, you should copy the php \ ext file and put it together with other dll files. Only in this way can phpinfo be displayed. Everyone thought it was not possible to copy the file to the directory at the bottom of the tutorial. In addition, xdebug. I tried to download the dll. for APACHE 2 of PHPnow, only XDEBUG can be downloaded. if the DLL 2.2.2 version is copied to the php ext version 2.2.3, phpinfo cannot be displayed and cannot be used.
