Steps to Install MySQLi Extension for PHP

Identify Installed PHP Version:

First, identify the PHP version currently installed on your system. You can do this by running:

php -v

This command will display the installed PHP version. Note down the version number (e.g., PHP 7.4, PHP 8.0, etc.).

Install MySQLi Extension for the PHP Version:

Based on your PHP version, install the corresponding MySQLi package. Replace phpX.X with your PHP version (e.g., php7.4-mysql for PHP 7.4):

sudo apt-get install php7.4-mysql  # Replace with your PHP version

Ensure that you use the correct package name that matches your PHP version installed on your system.

Restart Apache:

After installing the MySQLi extension, restart Apache to apply the changes:

sudo systemctl restart apache2

Verify Installation:

Create a PHP info file to verify that the MySQLi extension is now enabled:

echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/phpinfo.php

Access phpinfo.php via your web browser (http://your-ec2-instance-public-dns/phpinfo.php) and search for "mysqli" to confirm that the extension is enabled.
