How can PHP developers effectively troubleshoot and resolve database driver loading issues in PHP scripts?

When encountering database driver loading issues in PHP scripts, developers can troubleshoot and resolve the problem by checking if the necessary database driver extension is enabled in the PHP configuration file (php.ini). If the extension is not enabled, developers can enable it by uncommenting the corresponding line for the database driver extension and restarting the web server.

// Check if the necessary database driver extension is enabled
if (!extension_loaded('pdo_mysql')) {
    // Enable the PDO MySQL extension in php.ini
    // extension=pdo_mysql
    // Restart the web server
}
