# Try Out Development Containers: PHP

[![Open in Dev Containers](https://img.shields.io/static/v1?label=Dev%20Containers&message=Open&color=blue&logo=visualstudiocode)](https://vscode.dev/redirect?url=vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/microsoft/vscode-remote-try-php)

A **development container** is a running [Docker](https://www.docker.com) container with a well-defined tool/runtime stack and its prerequisites. You can try out development containers with **[GitHub Codespaces](https://github.com/features/codespaces)** or **[Visual Studio Code Dev Containers](https://aka.ms/vscode-remote/containers)**.

This is a sample project that lets you try out either option in a few easy steps. We have a variety of other [vscode-remote-try-*](https://github.com/search?q=org%3Amicrosoft+vscode-remote-try-&type=Repositories) sample projects, too.

> **Note:** If you already have a Codespace or dev container, you can jump to the [Things to try](#things-to-try) section.

## Setting up the development container

### GitHub Codespaces
Follow these steps to open this sample in a Codespace:
1. Click the Code drop-down menu and select the **Open with Codespaces** option.
1. Select **+ New codespace** at the bottom on the pane.

For more info, check out the [GitHub documentation](https://docs.github.com/en/free-pro-team@latest/github/developing-online-with-codespaces/creating-a-codespace#creating-a-codespace).

### VS Code Dev Containers

If you already have VS Code and Docker installed, you can click the badge above or [here](https://vscode.dev/redirect?url=vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/microsoft/vscode-remote-try-php) to get started. Clicking these links will cause VS Code to automatically install the Dev Containers extension if needed, clone the source code into a container volume, and spin up a dev container for use.

Follow these steps to open this sample in a container using the VS Code Dev Containers extension:

1. If this is your first time using a development container, please ensure your system meets the pre-reqs (i.e. have Docker installed) in the [getting started steps](https://aka.ms/vscode-remote/containers/getting-started).

2. To use this repository, you can either open the repository in an isolated Docker volume:

    - Press <kbd>F1</kbd> and select the **Dev Containers: Try a Sample...** command.
    - Choose the "PHP" sample, wait for the container to start, and try things out!
        > **Note:** Under the hood, this will use the **Dev Containers: Clone Repository in Container Volume...** command to clone the source code in a Docker volume instead of the local filesystem. [Volumes](https://docs.docker.com/storage/volumes/) are the preferred mechanism for persisting container data.

   Or open a locally cloned copy of the code:

   - Clone this repository to your local filesystem.
   - Press <kbd>F1</kbd> and select the **Dev Containers: Open Folder in Container...** command.
   - Select the cloned copy of this folder, wait for the container to start, and try things out!

## Things to try

Once you have this sample opened, you'll be able to work with it like you would locally.

> **Note:** This container runs as a non-root user with sudo access by default. Comment out `"remoteUser": "vscode"` in `.devcontainer/devcontainer.json` if you'd prefer to run as root.

Some things to try:

1. **Edit:**
   - Open `index.php`
   - Try adding some code and check out the language features.
   - Notice that PHP debugging and IntelliSense are already included in the container since the `.devcontainer/devcontainer.json` lists `"felixfbecker.php-debug"`, `"bmewburn.vscode-intelephense-client"`, and `"mrmlnc.vscode-apache"` as extensions to install automatically when the container is created.
1. **Terminal:** Press <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>\`</kbd> and type `uname` and other Linux commands from the terminal window.
1. **Run and Debug:**
   - Open `index.php`
   - Add a breakpoint (e.g. on line 4).
   - Press <kbd>F5</kbd> to launch the app in the container.
   - Once the breakpoint is hit, try hovering over variables, examining locals, and more.
1. **Running a server:**
   - From the terminal, run `php -S 0.0.0.0:8000`
   - Click "Open in Browser" in the notification that appears to access the web app on this new port.
      - You can view an organized table of your forwarded ports in the 'Ports' view, which can be accessed with the command **Ports: Focus on Ports View**.
      - Notice port 8000 in the 'Ports' view is labeled "Hello Remote World." In `devcontainer.json`, you can set `"portsAttributes"`, such as a label for your forwarded ports and the action to be taken when the port is autoforwarded.
   - Look back at the terminal, and you should see the output from your site navigations.
   - Edit the text on line 21 in `index.php` and refresh the page to see the changes immediately take effect.
1. **Attach debugger to the server:**
   - Follow the previous steps to start up a PHP server and open a browser on port `8000`
   - Press <kbd>F1</kbd> and select the **View: Show Debug** command.
   - Pick "Listen for XDebug" from the dropdown.
   - Press <kbd>F5</kbd> to attach the debugger.
   - Add a breakpoint to `index.php` if you haven't already.
   - Reload your browser window.
   - Once the breakpoint is hit, try hovering over variables, examining locals, and more.
