FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package framework
Utopia HTTP is a PHP MVC based framework with minimal must-have features for professional, simple, advanced and secure web development. This library is maintained by the Appwrite team.
Utopia HTTP is almost dependency-free. Any extra features, such as authentication or caching are available as standalone models in order to keep the framework core clean, light, and easy to learn.
Getting Started
Install using Composer:
Init your first application in src/server.php:
Run HTTP server:
Send HTTP request:
Server Adapters
The library supports server adapters to be able to run on any PHP setup. You could use the FPM or Swoole server.
Use PHP FPM server
When using PHP FPM, you can use the command
php -S localhost:80 src/server.phpto run the HTTP server locally
Using Swoole server
When using Swoole, you can use the command
php src/server.phpto run the HTTP server locally, but you need Swoole installed. For setup with Docker, check out our example application
Parameters
Parameters are used to receive input into endpoint action from the HTTP request. Parameters could be defined as URL parameters or in a body with a structure such as JSON.
Every parameter must have a validator defined. Validators are simple classes that verify the input and ensure the security of inputs. You can define your own validators or use some of built-in validators.
Define an endpoint with params:
Send HTTP requests to ensure the parameter works:
It's always recommended to use params instead of getting params or body directly from the request resource. If you do that intentionally, always make sure to run validation right after fetching such a raw input.
Hooks
There are three types of hooks:
- Init hooks are executed before the route action is executed
- Shutdown hooks are executed after route action is finished, but before application shuts down
- Error hooks are executed whenever there's an error in the application lifecycle.
You can provide multiple hooks for each stage. If you do not assign groups to the hook, by default, the hook will be executed for every route. If a group is defined on a hook, it will only run during the lifecycle of a request with the same group name on the action.
Hooks are designed to be actions that run during the lifecycle of requests. Hooks should include functional logic. Hooks are not designed to prepare dependencies or context for the request. For such a use case, you should use resources.
Groups
Groups allow you to define common behavior for multiple endpoints.
You can start by defining a group on an endpoint. Keep in mind you can also define multiple groups on a single endpoint.
Now you can define hooks that would apply only to specific groups. Remember, hooks can also be assigned to multiple groups.
Groups are designed to be actions that run during the lifecycle of requests to endpoints that have some logic in common. Groups allow you to prevent code duplication and are designed to be defined anywhere in your source code to allow flexibility.
Injections
Injections allow you to prepare dependencies for requests such as database connection or the user who sent the request. A new instance of a resource is created for every request.
We define an injection using a Container:
Inject resource into endpoint action:
Inject resource into a hook:
In advanced scenarios, resources can also be injected into other resources or endpoint parameters.
Resources are designed to prepare dependencies or context for the request. Resources are not meant to do functional logic or return callbacks. For such a use case, you should use hooks.

System Requirements
Utopia HTTP requires PHP 8.1 or later. We recommend using the latest PHP version whenever possible.
More from Utopia
Our ecosystem supports other thin PHP projects aiming to extend the core PHP Utopia HTTP.
Each project is focused on solving a single, very simple problem and you can use composer to include any of them in your next project.
You can find all libraries in GitHub Utopia organization.
