mcrypt

无法载入 mcrypt 扩展，
请检查 PHP 配置
出现以下几种情况后可能会造成运行phpmyadmin程序提示“无法载入 mcrypt 扩展，
请检查 PHP 配置”的错误提示

1、没有正确安装Mysql数据库，在系统服务中Mysql相关的服务没有启动（请查看正确安装Mysql的方法）

2、在系统的 system32（C:\windows\system32）目录下缺少 libmcrypt.dll文件，解决方法是找到php目录下的libmcrypt.dll，并将libmcrypt.dll复制到C:\windows\system32目录中，然后重新启动Web服务。

3、在C:\windows目录下的php.ini文件中，没有将“;extension=php_mcrypt.dll”中的前面一个“;”去掉，所以不能使用相应功能，解决方法是打开php.ini文件
找到
;extension=php_mcrypt.dll
改成
extension=php_mcrypt.dll //去掉前面的;使之生效

4、Mysql目录没有读取权限，正确的目录权限如下：
administrator 完全控制
system 完全控制

user 读取加运行
其他的用户权限全部删除（也可保留，但安全性不高，建议删除），然后重启MYsql服务和Web服务（建议修改此项后重启一下服务器）
当你试过所有办法之后还是不行,其实还有一步,网上很少有说,解决办法,我的是WINXP+IIS+PHP5+MYSQL5

桌面>我的电脑>右键属性>高级>环境变量>系统变量>新建

名:phprc
值:d:\php (你的PHP在什么目录就是什么)
