What are the best practices for managing PHP modules and extensions on a web server to prevent errors like the one described in the thread?

Issue: The error described in the thread is likely caused by missing or misconfigured PHP modules and extensions on the web server. To prevent such errors, it is crucial to properly manage and install the necessary PHP modules and extensions. Fix: To manage PHP modules and extensions effectively, you can use a package manager like `apt` on Ubuntu or `yum` on CentOS to install the required packages. Additionally, you can check the `php.ini` file to ensure that the necessary extensions are enabled. Regularly updating PHP and its extensions to the latest versions can also help prevent compatibility issues.

// Check if a PHP extension is installed
if (!extension_loaded('mysqli')) {
    die('The mysqli extension is not installed. Please enable it in your php.ini file.');
