phpMyAdmin 缺少 mysqli 扩展。请检查 PHP 配置 的解决方案 有需要的朋友可参考一下。

phpMyAdmin 缺少 mysqli 扩展。请检查 PHP 配置 的解决方案:
缺少 mysqli 扩展。请检查 PHP 配置。

打开你的php.ini->一般在C:WINDOWS目录下。
找到

 代码如下 复制代码
;extension=php_msql.dll
;extension=php_mssql.dll
extension=php_mysql.dll
extension=php_mysqli.dll

需要开启哪个扩展,就把这一行前面的分号去掉就行,注意要重启Apache 或者IIS


解决步骤:
1.看看php的ext目录中是否有php_mysqli.dll文件
如果有,继续下面的步骤。没有的话重新装个php
2.打开php.ini,找到

 代码如下 复制代码
;extension=php_mysqli.dll

把前面的分号";"去掉,改为

 代码如下 复制代码
extension=php_mysqli.dll

3.找到

 代码如下 复制代码
;extension_dir="./ext"

把前面的分号";"去掉,改为(相对于php的安装路径的ext目录)
extension_dir = "e:phpext"
e:php为php的存放目录

4.把php.ini拷贝到c:windows下

5.把libmysql.dll复制到Windows下面的System32目录(这个很关键)

6.重新启动IIS(不是网站)

cmd下运行 iisreset /RESTART 

如果上面方法还不行,可参考下面方法操作

第一步,输出 phpinfo() 看看 MySQL 模块是否成功装载,如果成功装载说明你见鬼了,否则看第二步,

IIS下phpinfo()无mysql模块是何原因?
原先用的php是.msi安装的,后来全部重来了一次,换成压缩包形式安装的。
又照着配置了php.ini,复制到winnt,复制libmysql.dll到system32。
之后测试成功。。。
第二步,查看 extension_dir 的设置是否正确
第三步,查看是否把 libmysql.dll 文件复制到 c:windowssystem32 下

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:windowssystem32) 目录下缺少 libmysql.dll文件,解决方法是找到php目录下的libmysql.dll,并将libmysql.dll复制到C:windowssystem32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_mysql.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


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。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
