How can the use of die() or other debugging techniques help identify issues in PHP scripts, particularly when dealing with image generation and display?

Using die() or other debugging techniques can help identify issues in PHP scripts by allowing you to pinpoint where the code is failing or encountering errors. When dealing with image generation and display, die() can be used to halt the script at a specific point to see if the image is being generated correctly or if there are any errors in the process. This can help in troubleshooting and fixing issues related to image generation and display in PHP scripts.

// Example code snippet demonstrating the use of die() for debugging image generation and display issues

$image = imagecreate(200, 200); // Create a blank image

if($image) {
    // Image generation code here
    
    // Display the image
    header('Content-Type: image/png');
    imagepng($image);
    imagedestroy($image);
} else {
    die('Error creating image.'); // Halt the script and display an error message if image creation fails
}
