在phpMyAdmin使用用户口令登陆
类别: PHP教程 
以下是我在管理过程中，根据实际需要，对phpMyAdmin做的一些更改，为了尽量不影响原来phpMyAdmin的结构，我在phpMyAdmin的基础上增加了一个文件index0.php，仅仅修改了一个文件config.inc.php，对phpMyAdmin没有一点影响，既可以使用原来的phpMyAdmin，也可以使用新的用户口令登陆机制。
以下为两个文件列表，将这两个文件拷贝到phpMyAdmin目录，执行index0.php即可，该程序在Apache + PHP + MYSQL 和 IIS5 + PHP + MYSQl 和 PWS + PHP + MYSQL下正常执行。
phpMyAdmin 下载：
