What are the best practices for handling user registration and profile creation in PHP to avoid issues with file management?

When handling user registration and profile creation in PHP, it's important to avoid storing user-uploaded files directly in the web server's public directory to prevent security risks and potential file management issues. Instead, it's recommended to store user files outside of the web root directory and use a database to store file paths for retrieval. 

// Example code snippet for handling user profile image upload and storage

// Define the directory where user profile images will be stored
$uploadDir = 'uploads/';

// Check if the directory exists, if not, create it
if (!file_exists($uploadDir)) {
    mkdir($uploadDir, 0777, true);
}

// Process file upload and move the file to the designated directory
if ($_FILES['profile_image']['error'] === UPLOAD_ERR_OK) {
    $fileName = $_FILES['profile_image']['name'];
    $fileTmp = $_FILES['profile_image']['tmp_name'];
    
    // Move the uploaded file to the designated directory
    move_uploaded_file($fileTmp, $uploadDir . $fileName);
    
    // Store the file path in the database for retrieval
    $filePath = $uploadDir . $fileName;
    
    // Save $filePath to the user's profile in the database
}
