# System Settings & CLI Integration

Multi-PHP provides a robust way to integrate your local development environment directly into your operating system's command line.

---

## 💻 CLI & System PATH Integration

Access your PHP and MariaDB binaries directly from any terminal window (CMD, PowerShell).

### Setting Up CLI Access:
1.  Navigate to `Settings > CLI & Environment Variables`.
2.  Enable **"System PATH Integration"**.
3.  Choose your **"Default PHP Version"** (this is what runs when you type `php` in a terminal).
4.  Choose your **"Default MariaDB Version"** (for `mysql` and `mariadb` commands).
5.  Click **"Sync Commands"** to apply changes.

### Generated Commands (Aliases):
Multi-PHP automatically creates and manages version-specific commands for you:
- `php83`: Triggers PHP 8.3 binary.
- `php74`: Triggers PHP 7.4 binary.
- `mysql`: Triggers default MariaDB client.

## 🛰️ Port Management & Remote Access

Each web and database server has its own port settings in `Settings > General`.

- **Nginx & Apache Ports**: Defaults to 80, but can be changed to 8080 or 8888.
- **MariaDB Port**: Defaults to 3306.
- **PHP-FPM Port**: Defaults to 9000.
- **Allow Remote Access**: When enabled, the software listens on `0.0.0.0` allowing other devices on your local network to access your development sites.

> [!WARNING]
> You must **restart your terminal windows** (CMD, PowerShell) for the PATH changes to take effect after clicking "Sync Commands".
