Ian P. Christian's personal blog

The headers Postini's anti-spam system adds to emails are quite hard to filter on, as you need to compare part of one header to part of another. Here's a little snipped that works with dovecot 1.2's sieve implementation. I don't actually use this myself anymore, but I'm posting it here for anyone else struggling with the problem.

Fabien has already introduced the symfony service container, and will be shortly releasing a post covering more of it. I was keen to get my hands dirty, so I've dived into the code and got a quick example working.

In a recent post about Symfony components - Fabien wrote about how the Symfony project (yes, that's right - a capital S now!) will be releasing more and more components. In this post I introduce sfYaml, a YAML parser for PHP - building on my previous blog post about routing.

symfony 1.2 was quite an improvement over 1.0, one of the most important changes was improved decoupling between components. In this article we're going to put this to the test and have some fun with sfRouting.

I've recently had the requirement to rate limit SOAP calls to a remote API, so having done the work I though I'd document it here.

I've recently done a little bit of SOAP work whilst spec'ing out a project for work - and I noticed that the PHP manual page for SOAP a mention of the 'classmap', which isn't documented so well. I thought I'd put an example here to show it's usage.

As you should be aware from my previous blog post - Bring Back Pirate Duck - one of my ducks is missing. This morning upon returning I found a small padded envelope addressed to 'Mr Ian P Christian - Duck Master".

I recently wanted to select a random row from a database, it seemed like a pretty trivial thing to do - but as often the case, it's not as easy as I first expected it to be!

In a previous post, "Playing with ActiveMQ using Maven", I showed how to produce and consume simple messages using Java. In this short post I show how to access these messages from PHP using STOMP.

In this post I demonstrate how to get started with ActiveMQ. This is very much a simple beginners guide, and shows you just enough to get a message traveling between 2 separate applications.

I've separated the example up into 3 sections. The 'producer' section will create test messages on a queue, the 'consumer' will consume them, and the final section, 'mq', will host the ActiveMQ instance. It would be possible to do this in a single application using an embedded broker, however I think it's useful to demonstrate them separately, as potentially the components could be on separate machines.
