Lorna Mitchell is back with a second installment in her "Building a RESTful PHP Server" series with this new post about handling and routing the incoming requests. (You can find the first part about working with the request here)

This is the second part of a series, showing how you might write a RESTful API using PHP. This part covers the routing, autoloading, and controller code for the service, and follows on from the first installment which showed how to parse the incoming request to get all the information you need.

She shows how to grab the controller name from the incoming request (based on her previous code), create the object for it and execute the requested action name. Also included is a sample autoloader and a basic controller - a UsersController with "getAction" and "postAction" methods for responding to GET and POST requests.

On her blog today Lorna Mitchell has a quick tip for anyone having an issue sending POSTed JSON data with the curl functionality that can be built into PHP. The trick to her method is sending things with the right header.

We can't send post fields, because we want to send JSON, not pretend to be a form (the merits of an API which accepts POST requests with data in form-format is an interesting debate). Instead, we create the correct JSON data, set that as the body of the POST request, and also set the headers correctly so that the server that receives this request will understand what we sent.

She includes a code example (about ten lines) showing the POSTing process that sets up options using curl's curl_setopt. Be sure to set up the headers to send as "application/json" - that's the trick to letting the remote end know the format.

On PHPBuilder.com today there's a new tutorial from Jason Gilmore about building a simple RESTful API with Slim, a microframework for PHP.

Although a relatively new entrant in the PHP framework sweepstakes, I've been lately quite intrigued by Slim, a slick RESTful microframework modeled after Ruby's Sinatra, which is coincidentally by far my favorite microframework available for any programming language. In this article I'll show you just how easy it is to get started building a powerful RESTful API using this streamlined framework.

Setup of the framework is as simple as downloading the latest copy from its github repository. It can then be included and used to make the simple routes in his examples. He uses a "games" request type to show how to handle GET, POST and PUT requests through Slim's simple interface.

On the Web Development Blog there's a recent post that shows you how to, with a simple bit of code, pull out the most popular posts to your WordPress blog.

Since I'm using WordPress.com Stats, I would like to use the rankings generated by this service or plugin. Searching Google, I found some widget called "WordPress.com Stats: Top Posts Widget" which works out of the box (if like to use a widget). In my case I have a custom sidebar with different custom sections using custom code. The following example explains how-to use that code on your website.

WordPress, by default, doesn't track any statistic information about the posts on your site, so you'll need something like the WordPress Stats plugin to get that part working. Once that's there, you can use his code to pull out the posts from the last few days (configurable) and show the most popular of the list.

In a new post to his blog today Chris Hartjes talks about the trials and tribulations he had when trying to test POST requests in his Zend Framework application with Zend_Test/PHPUnit.

I had done a refactoring of the way a model was pulling in stats for running backs and receivers for a fantasy game. As a result, in production (you suck Chris) you could not see results for those players. The data was there, I had not properly tested things. A familiar situation. So, I fixed the code and wrote my more-specific-than-before unit tests, but I decided I also wanted to make sure that the output on the page itself worked correctly. This began the descent into madness.

He found several examples of ways to test POST requests but none of them worked in his situation. They used an object chaining method that just didn't cooperate for him, so he figured out another way. The code for it's included in the post - it uses the getRequest method to set up and send the POST request.

Sameer Borate as a new post to his blog today looking at some of the quirks he's found when dealing with the $_POST superglobal in PHP.

A little quirk of PHP $_POST var I encountered while fixing a Salesforce web-to-Lead bug. A Wordpress site was using a form to submit user requests to the Salesforce web-service. The form that submitted the data had the following fields along with the others. The problem was with the multi-select field, only the last value selected in the multi-select was getting captured.

He investigated and found that his code was echoing out all of the values, but wasn't using the "field_name[]" notation with the square brackets to send back multiple values to PHP. Changing this and trying again, he noticed it still wasn't working as expected (with Salesforce). He figured out they're using "raw" versus "cooked" handling of the POSTed variables. Check out the rest of his post to find out what that means.

Lorna Mitchell has a new post to her blog looking at three different ways you can make a POST request to a server - cURL, Pecl_Http non-OOP and Pecl_Http with the OOP interface.

I've been doing a lot of work with services and working with them in various ways from PHP. There are a few different ways to do this, PHP has a curl extension which is useful, and if you can add PECL extensions then pecl_http is a better bet but there are a couple of different ways of using it. This post shows all these side-by-side.

Code snippets are included for each showing a request to the Flickr API. Be sure to check out the post's comments for more great ideas (like streams, the PEAR HTTP_Client package, Zend_Http_Client and other request types without cURL).

In a new post to his blog Ian Selby looks at working with REST requests in PHP. He includes some of the basics of REST too, for those not completely familiar with the term.

APIs have become a very commonplace part of many popular web sites and services...especially REST APIs. I've already discussed how you can roll your own REST API for your PHP apps, but I've also received countless requests to go over how to actually make RESTful requests. That's exactly what we'll take a look at in this article

His tool of choice is the curl extension, making it simple to create a class wrapper with methods like executePost, executeGet, setAuth and, of course, execute. He outlines the class and gives the code blocks that fit inside each of the major functions. In the end you'll have a class that can make GET, POST, PUT and DELETE requests and be able to correctly parse the response.
