This guide explains how to securely manage configuration and secrets in PHP during image manipulation processes using JavaScript.
<?php // Load environment variables require 'vendor/autoload.php'; use Dotenv\Dotenv; // Initialize dotenv and load the .env file $dotenv = Dotenv::createImmutable(__DIR__); $dotenv->load(); // Get secrets from environment variables $secretKey = $_ENV['IMAGE_SECRET_KEY']; $dbPassword = $_ENV['DB_PASSWORD']; // Configuration array $config = [ 'image_upload_path' => $_ENV['IMAGE_UPLOAD_PATH'], 'image_max_size' => $_ENV['IMAGE_MAX_SIZE'], 'allowed_formats' => ['jpg', 'png', 'gif'] ]; // Example function to manipulate images function manipulateImage($file) { global $config; // Validate the image format and size before manipulation $imageInfo = getimagesize($file['tmp_name']); $fileSize = $file['size']; if ($imageInfo && in_array($imageInfo['mime'], $config['allowed_formats']) && $fileSize <= $config['image_max_size']) { // Process the image (e.g., resize, crop, etc.) // Image manipulation logic goes here... } else { throw new Exception('Invalid image format or size exceeded.'); } } // Example usage of the image manipulation try { manipulateImage($_FILES['image']); } catch (Exception $e) { echo 'Error: ' . $e->getMessage(); } ?>
