php5.2.6安装配置xdebug 提示the requested operation has failed 解决办法

1、我选的最终版本：php_xdebug-2.1.0-5.2-vc6.dll
2、apache错误日志
      httpd.exe: Could not reliably determine the server's fully qualified domain name, using 172.10.84.73 for ServerName
      PHP Fatal error:  [Zend Optimizer] Zend Optimizer 3.3.0 is incompatible with Xdebug 2.1.0 in Unknown on line 0
3、最终确定这是和Zend Optimizer 3.3.0 冲突造成的
 
4、解决办法：
      [Zend]
zend_extension_manager.optimizer_ts="D:\website\ZendOptimizer\lib\Optimizer-3.3.0"
zend_extension_ts="D:\website\ZendOptimizer\lib\ZendExtensionManager.dll"
      注释掉上边两行，重启apache即可
