Lorna Mitchell has posted the last article in her look at web services - a focus on status codes.

Unlike the other posts in this series, this one is quite specific to one type of service - REST - since it deals with status codes, specifically HTTP ones. The ideas are transferrable however and other types of service can return statuses in a similar way.

She mentions things to keep in mind in returning the codes, some of the more interesting codes as well as some typical situations where things like an error code 500 would be thrown.

Status codes are like a headline to the calling entity about what happened, and are a valuable tool in the web service toolkit.

The PEAR blog has a quick note for users of PHP 5.3 and Windows:

Some users have reported that the windows builds of PHP 5.3 are not able to open the shipped go-pear.phar file.

If this is your situation, you can use their workaround (run the distributed phar version) or grab the non-pharred version.

John Lim has written up an article for the Oracle Technology Network about creating high performance systems with Oracle's Real Application Clusters (RAC) and PHP.

Running a software application that is able to work reliably through hardware and software failures is incredibly hard. [...] In this article, I will cover the network, architecture and design of our RAC application. Then I will discuss the real-world experiences and problems we experienced.

He details their RAC setup - load balancers, application servers and their RAC servers - before working through the different technologies and how they're all installed and configured to work together most efficiently.

After my colleague Cal reviewed DPC's tutorial day, it's now my turn to look back at the first real conference day of 2009's Dutch PHP Conference.

The day started with a nice movie made by Almer and Norman after which Cal officially opened the Dutch PHP Conference and introduced Andrei Zmievski to do the opening keynote. Andrei gave an outline of developments in PHP including the changes we are going to see in future versions. Closures, namespaces, better garbage collection and a few more things are coming to PHP5.3, but I think this isn't new to most people. I haven't really read a lot on PHP6 yet other than Unicode, so the addition of traits, C# style getters and setters and scalar/return value type hinting were new to me. I think this was a nice talk to be the opening keynote, because other than just being infomrative the talk also had the right amount of humor ......

In the next to last article of their loader series, DevShed looks at replacing some of the file loading functionality in their examples with functions from the SPL.

As I mentioned before, the Standard PHP library comes bundled with some helpful functions, such as "spl_autoload()," "spl_register_extension()" and "spl_autoload_register()" that allow you to either use a default implementation of the "__autoload()" function, or create a custom one for it.

Their example defines the extensions to use for autoloading and the name of the file/class to pull in. The rest is done automagically.

My article on High Performance and Availability with Oracle RAC and PHP is out on the Oracle web site. Enjoy.
