What considerations should be made when designing a PHP system to accommodate multiple images per database record and the use of separate tables for image management?

When designing a PHP system to accommodate multiple images per database record and the use of separate tables for image management, considerations should be made for efficient storage and retrieval of images. One approach is to have a separate table for storing image metadata (such as filename, path, and associated record ID) and another table for storing the actual image files. This allows for better organization and scalability when dealing with multiple images per record.

php 
// Example code snippet for storing image metadata in one table and image files in another table

// Database connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Insert image metadata into image table
$imageQuery = "INSERT INTO images (record_id, filename, path) VALUES (?, ?, ?)";
$stmt = $conn->prepare($imageQuery);
$stmt->bind_param("iss", $recordId, $filename, $path);

$recordId = 1; // ID of the associated record
$filename = "image.jpg"; // Image filename
$path = "/images/image.jpg"; // Image file path
$stmt->execute();

// Insert image file into files table
$fileQuery = "INSERT INTO image_files (image_id, file_data) VALUES (?, ?)";
$stmt = $conn->prepare($fileQuery);
$stmt->bind_param("ib", $imageId, $fileData);

$imageId = $conn->insert_id; // ID of the inserted image metadata
$fileData = file_get_contents("/path/to/image.jpg"); // Get image file data
$stmt->send_long_data(1, $fileData);
$stmt->execute();

// Close connection
$conn->close();
