How can a beginner in PHP effectively handle error messages and troubleshoot issues in their code?

To effectively handle error messages and troubleshoot issues in PHP, beginners can use error reporting functions like error_reporting() and ini_set('display_errors', 1) to display errors on the screen. Additionally, beginners can use try-catch blocks to catch exceptions and handle them gracefully. Finally, beginners can use tools like Xdebug to step through their code and identify issues.

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

// Example try-catch block
try {
    // Your PHP code here
} catch (Exception $e) {
    echo 'Caught exception: ' . $e->getMessage();
}

// Example of using Xdebug for debugging
// Install Xdebug extension and configure your IDE for debugging
// Use breakpoints to step through your code and inspect variables
