How can one ensure that the necessary MySQL module is included in PHP to avoid undefined function errors?

To ensure that the necessary MySQL module is included in PHP to avoid undefined function errors, you need to make sure that the MySQL extension is enabled in your PHP configuration. This can be done by ensuring that the `php_mysql` extension is installed and enabled in your `php.ini` file. Once the extension is enabled, you should no longer encounter undefined function errors related to MySQL functions in your PHP code. 

// Check if the MySQL extension is enabled
if (!function_exists('mysqli_connect')) {
    die('MySQL extension is not enabled. Please enable the php_mysql extension in your php.ini file.');
}

// Your PHP code using MySQL functions can go here
