在phpMyAdmin使用用戶口令登陸

使用過phpMyAdmin的人知道，在phpMyAdmin中，使用文件config.inc.php保存用戶名和密碼，當需要更換用戶或用戶口令更改時，必須修改config.inc.php文件，然后再上傳，特別的不方便。更有時，為了修改MYSQL庫或表而使用root賬號，如果這時其它網站的自動搜擎系統搜索到index.php并繼續執行其中的每一步的話，是相當危險的。為此需要用戶登陸機制，在每次使用時，輸入用戶名和口令，這樣會安全得多。
以下是我在管理過程中，根據實際需要，對phpMyAdmin做的一些更改，為了盡量不影響原來phpMyAdmin的結構，我在phpMyAdmin的基礎上增加了一個文件index0.php，僅僅修改了一個文件config.inc.php，對phpMyAdmin沒有一點影響，既可以使用原來的phpMyAdmin，也可以使用新的用戶口令登陸機制。
以下為兩個文件列表，將這兩個文件拷貝到phpMyAdmin目錄，執行index0.php即可，該程序在Apache + PHP + MYSQL 和 IIS5 + PHP + MYSQl 和 PWS + PHP + MYSQL下正常執行。
