How can beginners effectively troubleshoot and debug PHP code when integrating third-party services like PayPal?

Beginners can effectively troubleshoot and debug PHP code when integrating third-party services like PayPal by using error reporting functions, checking for syntax errors, and utilizing debugging tools like Xdebug. Additionally, logging errors to a file or outputting them to the browser can help identify issues in the code. 

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Check for syntax errors
if (ini_get('display_errors')) {
    echo "Syntax errors found!";
}

// Implement Xdebug for debugging
xdebug_start_trace();

// Log errors to a file
ini_set('error_log', 'error.log');
