# Try Out Development Containers: PHP
This is a sample project that lets you try out the **[VS Code Remote - Containers](https://aka.ms/vscode-remote/containers)** extension in a few easy steps.
> **Note:** If you're following the quick start, you can jump to the [Things to try](#things-to-try) section.
## Setting up the development container
Follow these steps to open this sample in a container:
1. If this is your first time using a development container, please follow the [getting started steps](https://aka.ms/vscode-remote/containers/getting-started).
2. To use this repository, you can either open a locally cloned copy of the code:
- Clone this repository to your local filesystem.
- Press F1 and select the **Remote-Containers: Open Folder in Container...** command.
- Select the cloned copy of this folder, wait for the container to start, and try things out!
Or open the repository in an isolated Docker volume:
- Press F1 and select the **Remote-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 **Remote-Containers: Open Repository in Container...** command to clone the source code in a Docker volume instead of the local filesystem.
## Things to try
Once you have this sample opened in a container, 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.
