Enable MySQLi Extension in PHP 7

Issue:

Upon installing PHP 7 and MySQL 5.5.47 on Ubuntu 14.04, you may encounter a missing MySQLi extension, hindering the use of phpMyAdmin.

The php5-mysql package is no longer supported in PHP 7. To enable MySQLi, install the following package:

sudo apt-get install php-mysql

This package includes both MySQL and MySQLi drivers, and will automatically update Apache and PHP 7.

Verification:

To confirm that MySQLi is enabled, you can use phpinfo():

<?php
phpinfo();
?>

Look for the "mysqli" section in the output to verify that the extension is loaded.
