What are the best practices for error handling and debugging in PHP when dealing with code that involves image creation and manipulation?

When dealing with image creation and manipulation in PHP, it is crucial to implement proper error handling and debugging techniques to catch any potential issues that may arise, such as invalid image formats or missing files. One of the best practices is to use try-catch blocks to handle exceptions and display meaningful error messages to the user or log them for further investigation. 

try {
    // Code for image creation and manipulation
    // For example, loading an image from a file
    $image = imagecreatefromjpeg('example.jpg');
    
    // Code for image manipulation
    // For example, resizing the image
    $resizedImage = imagescale($image, 200, 150);
    
    // Code for saving the manipulated image
    // For example, saving the resized image to a new file
    imagejpeg($resizedImage, 'resized_example.jpg');
    
    // Output success message
    echo 'Image manipulation successful!';
} catch (Exception $e) {
    // Output error message
    echo 'An error occurred: ' . $e->getMessage();
}
