## 🛠️ Development Commands ## 🛠️ Development Commands
| Type | Command | Notes | - **Dependencies:** `composer install` / `update` (updates after editing composer.json)
| :--- | :--- | :--- | - **Linting:** N/A (adhere to PSR-12 manually)
| **Dependencies** | `incus exec www composer install` / `incus exec www composer update` | Run from the host machine. Apache2 with PHP/Composer runs in the INCUS container 'www'. The folder ./ is shared with /var/www/localhost/ in the container, and port 80 is shared with the host. Use `update` after editing `composer.json`. | - **Testing:** `curl localhost` (no framework; run manual scripts like `php test.php` for single tests)
| **Linting** | N/A | No dedicated tool. Adhere to PSR-12 standards. | - **Build:** N/A (direct PHP execution)
| **Testing** | `curl localhost` | No testing framework configured. Avoid adding tests until one is introduced. | - **Version Control:** `git status` / `add` / `commit` / `push`
