phpMyAdmin“无法载入mysql扩展,请检查PHP配置”的解决方法

在配置了PHP的运行环境,并且安装了MySQl数据库之后,下面就可以学习下PHP如何与MySQL进行交互了。

既然MySQL是数据库,则必不可少的需要建立数据库、表、字段等操作(假象下我们使用ASP+ACCESS的情形),然而对于MySQL数据库而言,在我们默认安装时是没有可视化界面操作MySQl的,所以我们很多时候是借助phpMyAdmin来操作MySQL数据库的。

然而通过“PHP 5.2.3 installer”安装版的使用,当我们应用到phpMyAdmin,页面出现了“无法载入mysql扩展,请检查PHP配置”的提示。

1,首先,我们就来检查PHP配置文件 php.ini

打开PHP所安装目录下的 php.ini 文件,Ctrl+F搜索“php_mysql.dll”,将“;extension=php_mysql.dll”前的“;”删除以取消注释,同时搜索并修改“extension_dir”的值为“php_mysql.dll”文件所在文件夹。即:

extension_dir = "D:\PHP\ext\"

extension=php_mysql.dll

2,然而通过这一页所使用的安装版是没有保存PHP扩展DLL文件的ext文件夹的,所以也就没有php_mysql.dll,我们运行phpMyAdmin当然会有问题

继续打开http://www.php.net/downloads.php 选择“PHP 5.2.3 zip package”压缩包文件,将其中的ext文件夹全部解压到PHP的安装目录下,所以才有了extension_dir = "D:\PHP\ext\"(注:前提是你的PHP安装在D盘)

3,完成了对php.ini文件的修改和包含有php_mysql.dll的ext文件夹的添加,建议重新启动下计算机,再来调试phpMyAdmin

4,当然,对于phpMyAdmin文件夹内的config.inc.php文件进行MySQL帐号和密码的修改。

另外,在网络上搜索了下本问题的相关解决方法,有的解决还需要把“php.ini文件和php_mysql.dll拷贝到了c:/windows以及c:/windows/system32目录”内,这是由于PHP是非安装版,一般安装版则不需要了,你可以在“我的电脑”属性“高级”中选择“环境变量”查看系统变量“Path”其中就指明了PHP的安装路径。

phpMyAdmin“无法载入mysql扩展,请检查PHP配置”的问题解决(感谢含笑的指导参考),下面可以学习使用PHP与MySQL交互操作了。
