IMPORTANT: Backend Configuration Update Required

After converting from Node.js to PHP backend, you need to:

1. Create a .env file in the client directory with the following content:

VITE_BACKEND_URL=http://localhost/api

2. For production, update the URL to your actual domain:

VITE_BACKEND_URL=https://your-domain.com/api

3. No changes are needed in the React components - they will automatically use the new PHP backend once the .env file is created.

The PHP backend is fully compatible with all existing frontend API calls.
