Download the PHP package slick/http without Composer

Slick HTTP

slick/http provides a complete implementation of PSR-7 (HTTP Message Interface) and PSR-18 (HTTP Client Interface), enabling developers to work seamlessly with HTTP messages and clients in a standardized way. By adhering to these PSR standards, the library ensures interoperability with other libraries and frameworks that follow the same specifications, promoting code reusability and consistency across projects. In addition, the library includes an HTTP server that functions as a middleware runner, allowing you to pass a collection of middleware objects to the server, which are called in sequence to compose a response for the current server request. This middleware approach provides a flexible, modular way to handle HTTP requests, enhancing the scalability and maintainability of your PHP applications.

This package is compliant with PSR-2 code standards and PSR-4 autoload standards. It also applies the semantic version 2.0.0 specification.

Usage

Server Request Message

This is an handy way to have a HTTP request message that has all necessary information that was sent by the client to the server.

Its very simple to get this:

The $request encapsulates all data as it has arrived at the application from the CGI and/or PHP environment, including:

• The values represented in $_SERVER.
• Any cookies provided (generally via $_COOKIE)
• Query string arguments (generally via $_GET, or as parsed via parse_str())
• Upload files, if any (as represented by $_FILES)
• Deserialized body parameters (generally from $_POST)

Consider the following message:

Now lest retrieve its information using the $request object:

HTTP Server

The HTTP server is a middleware runner. You can pass a collection of middleware objects to the server and they all will be called in their sequence in order to compose a response for current server request.

Lets create a simple web application that will print out a greeting to a query parameter named 'name'. Lets first create our middleware classes:

This middleware retrieves the query parameter with name and add an attribute to the request object passed to the next middleware in the stack. Lets create our printer:

Now lets create our main server application:

HTTP Client

Working with HTTP requests (as a client) is one of the most common tasks nowadays. Almost every application need to retrieve data from a web service or API and therefore an HTTP client is a must have.

Slick\Http\Client\CurlHttpClient implments PSR-18 HTTP Client

It depends on PHP's cURL extension to connect and make HTTP requests. Lets see an example:

Session

Slick\Http\Session has a very simple and ease implementation. By default it will use the PHP session handling and it comes with a simple factory that you can use to create it:

Write session data

Read session data

Deleting session data

You can create your own session drivers if you need to encrypt you data or change the save handler to save in a database by simply implementing the Slick\Http\Session\SessionDriverInterface. It also comes with a Slick\Http\Session\Driver\AbstractDriver class that has all the basic operations of the interface already implemented.
