When you open phpmyadmin, you may get an error like this,
Missing mysqli extension. Please check PHP configuration.
You can check according to the following methods:
1.Check whether php.ini ;extension=php_mysqli.dll is enabled, that is, remove the previous;
2.Check whether the php.ini extension_dir address points to the ext directory of the php directory. This step is the key. I am at this step. I set extension_dir = "e:wwwphp54ext" Just make it your own directory
3.Check whether lib_mysql.dll has been copied to the windows directory. This dll file comes in many forms, including libmysql_d.dll without underlining, so be careful to read it yourself
4.Check whether the php_mysqli.dll file exists in the ext directory of the PHP installation directory. It is also stated on the Internet that it is best to use the zip package to decompress without file loss
5.Check the php details page to see if mysql and mysqli have been started. This step is to check whether you have enabled mysqli
No If it is turned on, you will not be able to see the mysqli keyword on the PHP detailed page
Final note! ! ! ! Restart Apache
