我安装的是PHP Version 5.3.26，按照网上提示在Eclipse中使用XDebug进行调试，不过配置了却使用不了，下面把解决方法简要说一下。
XDebug老是加载不了
From PHP 5.3 onwards, you always need to use the zend_extension PHP.ini setting name, and not zend_extension_ts, nor zend_extension_debug. However, your compile options (ZTS/normal build; debug/non-debug) still need to match with what PHP is using.
Php.ini中的配置
;debug configuration
zend_extension="D:/servers/php-5.3.8/ext/php_xdebug-2.1.3-5.3-vc9.dll"
;xdebug配置
[Xdebug]
xdebug.remote_enable=1
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.auto_trace = On
xdebug.show_exception_trace = On
xdebug.remote_autostart = On
xdebug.collect_vars = On
xdebug.collect_return = On
xdebug.collect_params = On
Eclipse配置
在eclipse的项目里的Properties里面找到"PHP Debug"，在PHP Debugger里面选择"XDebug"
再配置一下：
再在Windows->Preferences里面配置下PHP Servers
