What are best practices for error reporting in PHP to troubleshoot issues like image creation failures?

When troubleshooting image creation failures in PHP, it is important to implement proper error reporting to identify the root cause of the issue. One best practice is to enable error reporting and display error messages to help pinpoint where the problem occurs in the code. Additionally, logging errors to a file can provide a detailed record of any issues that arise during image creation.

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

// Log errors to a file
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Code for image creation
$image = imagecreatefromjpeg('image.jpg');
if(!$image) {
    trigger_error('Failed to create image', E_USER_ERROR);
}
