- Security recommendations
- Testing procedures

**README_PHP.md**
- Quick start guide
- File overview
- Key changes summary

## 🔄 Key Differences

### Before (Node.js)
```javascript
// server.js - Single file with Express
const express = require('express');
const nodemailer = require('nodemailer');

// Dependencies: express, cors, nodemailer, dotenv
// Deployed on: Railway, Vercel, or Node.js hosting
// Email: Using SMTP with nodemailer
```

### After (PHP)
```php
// booking.php, contact.php - Multiple files
<?php
header('Content-Type: application/json');

// Dependencies: None (pure PHP)
// Deployed on: Any shared hosting with PHP support
// Email: Using native mail() function
```

## 📦 File Structure

OLD FILES (still present):
├── server.js                # OLD: Node.js server
├── package.json             # OLD: npm dependencies
└── node_modules/            # OLD: npm packages
```

## 🎯 Features Maintained

✅ All original features preserved:
- Booking form handling
- Contact form handling
- Email notifications to admin
- Customer confirmation emails
- Beautiful HTML email templates
- Form validation
- CORS support
- Error handling
- Input sanitization

✅ New advantages:
- No dependencies required
- Works on shared hosting
- Lower hosting costs
- Easier deployment
- Native PHP mail support
- Better for static + PHP setups

## ⚠️ Important Notes

### 1. Frontend Updates Needed

The React components (`BookingForm.tsx` and `Contact.tsx`) still point to the Railway backend:

```javascript
// Current (Railway)
const apiUrl = 'https://taxiagadir-production.up.railway.app/api/booking';

// Should be changed to (your domain)
const apiUrl = '/api/booking';
// or
const apiUrl = 'https://taxiagadirairport.com/api/booking';
```

### 2. Email Configuration

PHP's `mail()` function requires server-side configuration:

- **Shared hosting**: Usually pre-configured
- **VPS/Dedicated**: May need SMTP setup
- **See**: PHP_DEPLOYMENT_GUIDE.md for details

### 3. File Permissions

Set appropriate permissions:
- PHP files: `644`
- `.htaccess`: `644`
- `.env`: `600` (restricted)

### 4. Testing Checklist

Before going live:
- [ ] Test booking form submission
- [ ] Test contact form submission
- [ ] Verify emails are received
- [ ] Check email formatting
- [ ] Test error handling
- [ ] Verify CORS headers
- [ ] Test from different browsers
- [ ] Check mobile responsiveness
- [ ] Review error logs
- [ ] Test health endpoint

## 🚀 Deployment Steps

1. **Create `.env` file** with email credentials
2. **Configure PHP mail()** on your hosting
3. **Upload PHP files** to server
4. **Set file permissions** correctly
5. **Update frontend** API URLs
6. **Test all endpoints** thoroughly
7. **Monitor logs** for errors
8. **Go live!** 🎉

See **PHP_DEPLOYMENT_GUIDE.md** for detailed instructions.

## 📊 Code Statistics

| Metric | Node.js | PHP |
