Abstract
There has been a lot of talk over the past several years about the difference between performance and scalability. When talking about building a scalable application queuing is a concept that many PHP developers are not overly familiar with. In this talk we will demonstrate how you can use the Zend Server Job Queue to scale your application.

I saw on a StackOverflow posting, someone was asking to see how you could use a Zend Framework validator to tell if an IP address was between two addresses. The individual was trying to use Zend_Validate_Between to do the checking. However, IP addresses generally are not checked between two arbitrary addresses such as between 192.168.0.45 and 192.168.0.60. Instead, the check is usually done to validate an IP address against a subnet.

Abstract
The object-relational impedance mismatch makes persisting PHP objects in a relational database a daunting task. How about these new schemaless NoSQL databases? We will have a look at the problems involved with persisting PHP objects, and introduce design patterns that help solving these problems. Putting the patterns to good use, we will build a working PHP object persistence solution for MongoDB.

I just had an epiphany. I’ve talked about pre-caching content before and the benefits thereof before. But this is the first time I realized not only that there are benefits, but that doing it is BETTER than caching inline. Let me sum up… no, there is to much. Let me explain.
Typically caching is done like this (stolen from the ZF caching docs):
Just a real quick note. I received the podcasts from ZendCon 2010 back in December and opened up a contest to let people choose which order they wanted to hear the sessions in. The order is in and I have already started posting them, starting with Dependency Injection. I would have done the Unit Testing after ZF 1.8 but Michelangelo is doing a webinar with us on the 19th, so I will post the recording of his ZendCon session afterwards.

Abstract
This session introduced one of the less-known design patterns in the PHP world, but also one that can greatly improve the decoupling and the testability of your code: Dependency Injection. I will demonstrate how to use Dependency Injection in your projects, and I will take advantage of the PHP 5.3 new features to create a fully-featured DI container live.

In case you didn’t know, I also write music. 🙂 I probably talk about it more than some of the readers of this blog wish. But, you know what? I just really enjoy writing music. I may not be particularly good at it, but it’s enjoyable… at least when it’s done.
Last year ( it is now 2011 ) I released an album called Coronal Loop Safari right prior to Zendcon and Zend was kind enough to let me play the songs from the album prior to each keynote. But, that’s really not enough to hear what the album is like. In fact, I really don’t know what the album sounds like. But here’s what I wrote about it on my CD Baby album page.
Earlier in December I did a webinar on the Zend PHP Cloud Application Platform. It’s not some new product or anything like that, but rather a view of how our software is going to fit together. It’s not something that will be “released” in the typical software fashion. Instead it is the mindset of our product development teams when they look at building new features. Cloud-based pricing for Zend Server, AWS/Cloud integration in Zend Studio, and, of course, SimpleCloud.
In the previous installment I talked a little about the cloud, what Zend is doing in the cloud and what the example application for my ZPCAP webinar did. One of the primary characteristics of scalability is the ability to process data as resources are available. To do that I implemented the Zend Server Job Queue with an abstraction layer that I’ve written about three different versions for. I think the fourth will be the charm :-).
We have so far looked at setting the stage and managing the job. How about executing the job itself? The job we will look at here will be relatively generic. I will get into more detail after I have talked about the SimpleCloud elements. This, here, is simply to show you the theory behind how jobs are executed.
The abstract class is pretty simple.
