<?php // Example: Effective logging in PHP image manipulation // Function for image upload with error logging function uploadImage($file) { $logFile = 'error_log.txt'; // Log file path // Check if the file is uploaded if (!isset($file['tmp_name']) || !file_exists($file['tmp_name'])) { file_put_contents($logFile, "Error: No file uploaded.\n", FILE_APPEND); return false; } // Image processing $image = imagecreatefromjpeg($file['tmp_name']); if (!$image) { file_put_contents($logFile, "Error: Invalid image file.\n", FILE_APPEND); return false; } // Continue with image manipulation, or save the image // For demo, we'll save the image $outputPath = 'uploads/' . basename($file['name']); if (!imagejpeg($image, $outputPath)) { file_put_contents($logFile, "Error: Failed to save image.\n", FILE_APPEND); return false; } imagedestroy($image); return true; } // Usage example if ($_SERVER['REQUEST_METHOD'] === 'POST') { uploadImage($_FILES['image']); } ?>
