Michael Dowling:
Guzzle 5 and RingPHP
Oct 14, 2014 @ 10:52:25

Michael Dowling has a new post to his site today talking about the latest release for the Guzzle HTTP library and how it now works with RingPHP to make integration life easier. The RingPHP library, inspired by Clojure's Ring library, provides a low-level structure to work with HTTP clients and servers through a simple interface.

With RingPHP, Guzzle does not require cURL and can be used with any HTTP transport mechanism. I’d love to help anyone who is interested in creating RingPHP adapters to bind Guzzle to another library. For example, WyriHaximus on Github is working on binding Guzzle to ReactPHP. (In fact, Guzzle 4 did not require cURL, though it was much harder to use an alternate transport.)

He goes on to talk more about the changes in the Guzzle 5 release including more detail on the RingPHP integration, the use of promises/futures and iterable and callable streams. There's also several new events included in the release as well. He finishes out the post with an upgrade guide to help make the transition easier.

Michael Dowling:
Guzzle-Ring and Future Responses
Sep 30, 2014 @ 09:36:32

Michael Dowling has a new post to his site today talking about the work that's being done on the upcoming release of the Guzzle HTTP client. In the post he talks about a major change in how it allows for asynchronous requests and the work on Guzzle-Ring to make it happen.

Guzzle 4 has been out for a little over six months. It has proven to be leaps and bounds better than Guzzle 3, and I’ve been very happy with the design so far. However, after the release of Guzzle 4, I’ve received feedback from numerous members of the PHP community that can be boiled down to “Guzzle needs async support.” While Guzzle has always had the ability to send requests concurrently using a pool of requests, there was not a way to send asynchronous requests.

After a couple months of work and borrowing concepts from Clojure, I’ve created Guzzle-Ring, an extremely simple adapter and middleware library for PHP (not just Guzzle) that can power both clients and servers for both synchronous and asynchronous requests.

The Guzzle-Ring reduces the need for the previous complexity of creating multiple adapters, which ended up with the adapters knowing too much about the request itself. He introduces the Guzzle-Ring system that will be included in Guzzle v5, heavily influenced by Clojure. The adapter makes the request as simple as passing in an array and makes use of "futures" to handle the request/response cycle. He also talks some about creating middleware piece that helps integrate it into your application, wrapping functionality inside of another method. He illustrates all of this with code examples and includes others such as fetching of future responses, sending requests concurrently and the Guzzle-Ring server adapters.
