What are some best practices for organizing and storing user-uploaded images in a PHP-based gallery?

Organizing and storing user-uploaded images in a PHP-based gallery requires a structured approach to ensure efficient retrieval and management of images. One best practice is to create a folder structure based on categories or tags to organize images. Additionally, storing image metadata in a database can help with searching and filtering images. It is also important to validate and sanitize user inputs to prevent security vulnerabilities. 

// Example code snippet for organizing and storing user-uploaded images in PHP

// Define the base directory for storing images
$uploadDir = 'uploads/';

// Create a function to generate a unique filename for each uploaded image
function generateUniqueFilename($filename) {
    $extension = pathinfo($filename, PATHINFO_EXTENSION);
    $uniqueFilename = uniqid() . '.' . $extension;
    return $uniqueFilename;
}

// Process the uploaded image and move it to the appropriate folder
if(isset($_FILES['image'])){
    $image = $_FILES['image'];
    $imageName = generateUniqueFilename($image['name']);
    $uploadPath = $uploadDir . $imageName;
    
    if(move_uploaded_file($image['tmp_name'], $uploadPath)){
        // Save image metadata to database
        // Insert query to store image details in database
    } else {
        echo 'Failed to upload image';
    }
}
