What are some best practices for debugging and error handling when working with ImageTTFText in PHP?

Issue: When working with ImageTTFText in PHP, it's important to properly handle errors and debug any issues that may arise to ensure smooth execution of the script. Best practice for debugging and error handling: 1. Use error_reporting() function to enable error reporting and display errors. 2. Implement try-catch blocks to catch and handle exceptions that may occur during the execution of the script. 3. Use var_dump() or print_r() functions to inspect variables and identify any potential issues. PHP code snippet: 

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

// Example of using try-catch block for error handling
try {
    // Your ImageTTFText code here
    $image = imagecreatefrompng('example.png');
    $textColor = imagecolorallocate($image, 255, 255, 255);
    imagettftext($image, 20, 0, 10, 50, $textColor, 'arial.ttf', 'Hello World');
    
    // Output the image
    header('Content-type: image/png');
    imagepng($image);
    imagedestroy($image);
} catch (Exception $e) {
    echo 'An error occurred: ' . $e->getMessage();
}
