Phpmyadmin reports "the mysqli extension is missing. Check the PHP configuration "-php Tutorial

Phpmyadmin reports "the mysqli extension is missing. Check the PHP configuration "1. First, check the mysql dll and mysqli. dll services in php. ini except the semicolon php installation package.
2. the following paths are correct about apache configurations.
LoadModule php5_module "D:/php/php5.4/php5apache2_2.dll"
AddType application/x-httpd-php. php
AddType application/x-httpd-php. htm
PHPIniDir "D:/php/php5.4/php. ini"
LoadFile "D:/php/php5.4/php5ts. dll"
DocumentRoot "G: \ php_project"
But the error is returned.

Phpinfo (); check if the mysqli extension is loaded.

It's strange that my service was launched.

Check whether php. ini in the Loaded Configuration File is the File you modified.

I have not changed
Only the service and specified ext path are added to php. ini.

Loaded Configuration File (none)
Many online practices are to put php. ini in the windows directory on drive C.
But this is different because I started php. ini in apache when I started apache, so I didn't need to place php. ini into drive C, so I didn't do that.

PHPIniDir "D:/php/php5.4"
Instead
PHPIniDir "D:/php/php5.4/php. ini"

PHPIniDir
Directory where php. ini is located

The reason is that I accidentally added "." to the php. ini file and wrote "php. ini"
Therefore, Loaded Configuration File (none) appears)
