How to enable MySQLi? Before going to enable it on the server, I will share some ideas about MySQLi. Then, I should explain how we can enable MySQLi on a cpanel server and How we can check if MySQLi is already enabled or not in the server.
What is MySQLi?
Simply it’s a MySQL extension for PHP programming language. The MySQLi Extension (MySQL Improved) is a relational database driver used in the PHP programming language to provide an interface with MySQL databases.
The developers of the PHP programming language recommend using MySQLi when dealing with MySQL server versions 4.1.3 and newer (takes advantage of new functionality). The MySQLi extension has a lot of benefits, some of them are listed below:
- An object-oriented interface
- Support for prepared statements
- Support for multiple statements
- Support for transactions
- Enhanced debugging support
- Embedded server support
- Powerful Functionality
How to check the MySQLi extension is enabled or not on server?

Accessing PhpMyAdmin without cPanel login?
This article will help you to access databases of cPanel users’ without accessing the cPanel account.
Consider the scenario, you’ve a cPanel account and you want to share the details of a database (DB) with one of your we site developers and actually you do not want to share the cPanel credentials.
In EasyApache 4, the mysqli extension is provided by the mysqlnd package. To illustrate this, here is a list of the files that are provided by the ea-php55-php-mysqlnd package.
# rpm -ql ea-php55-php-mysqlnd
/opt/cpanel/ea-php55/root/etc/php.d/mysqlnd.ini
/opt/cpanel/ea-php55/root/etc/php.d/mysqlnd_mysql.ini
/opt/cpanel/ea-php55/root/etc/php.d/mysqlnd_mysqli.ini
/opt/cpanel/ea-php55/root/etc/php.d/pdo_mysqlnd.ini
/opt/cpanel/ea-php55/root/usr/lib64/php/modules/mysqlnd.so
/opt/cpanel/ea-php55/root/usr/lib64/php/modules/mysqlnd_mysql.so
/opt/cpanel/ea-php55/root/usr/lib64/php/modules/mysqlnd_mysqli.so
/opt/cpanel/ea-php55/root/usr/lib64/php/modules/pdo_mysqlnd.so

Thanks Man this really helped me as I needed to relocate one of my wordpress websites using the Duplicator plugin and i was jammed up due the the MySQLi Extension not running. Your guide made it very easy for me and I’m not a server guy 🙂 Thanks!
Thanks for your feedback Kamal.
Hi
Just wondering if rebuilding the web-server with easyapache erases any current mysql database you have up?
Cheers
Nope. Executing EasyApache won’t delete any of your databases.
Perfect. Accurate and straight to the point!
Hello Ayman,
Thanks for your feedback 🙂
You are welcome 🙂

If you have CloudLinux, you can change the PHP version from cPanel itself. Also check the MySQL version “mysql -V”.

I think they have CloudLinux, so you can manage it from the cPanel itself.

I am having this problem “Your PHP installation appears to be missing the MySQL extension which is required by WordPress” when I’m upgrade the php from version 5.6 to 7.2. Turns out that mysql extension is no longer supported in php version 7.2. It is now using mysqli extention. I am using old version of wordpress which still using mysql extension so the problem existed. So what I did is upgraded the wordpress to the core. I used the latest version of wordpress and used filezilla to put the new version to the site. I only overwrite the folder wp-includes and wp-admin and replace all the files in the root folder with the new files from version 7.2
