To install Alt-PHP packages on a CloudLinux server, follow these steps:

1. Access Alt-PHP Manager: Log in to your server's control panel (such as cPanel or Plesk) and navigate to the Alt-PHP Manager. This is where you can select and manage different PHP versions.

2. Select Alt-PHP Version: Choose the Alt-PHP version for which you want to install additional packages. Make sure you're working with the correct PHP version.

3. Access Shell (Terminal) or SSH: Open a terminal or connect to your server via SSH. This is where you'll execute the necessary commands.

4. Update Package Lists: Before installing any package, it's a good practice to update the package lists to ensure you're getting the latest version. Run the following command:

   bash

• yum update

• Install Alt-PHP Packages: Use the yum package manager to install Alt-PHP packages. The packages are typically named in the format alt-phpXX-package_name, where XX represents the PHP version (e.g., alt-php73 for PHP 7.3).

  For example, if you want to install the php-mysqlnd package for PHP 7.3, you would use:

  bash
• yum install alt-php73-php-mysqlnd

  Replace XX with the appropriate PHP version.

• Verify Installation: After installation, you can verify that the package has been installed correctly by using the appropriate command for the specific package.

• Integrate Package with Your PHP Application: Depending on the package, you'll need to integrate it into your PHP application. This might involve including it in your code or configuring it through specific settings.

• Restart Web Server: After installing any packages, you'll likely need to restart your web server for the changes to take effect. Use one of the following commands based on your web server:

  For Apache:

  bash

For Nginx with PHP-FPM:
