The Developer Tutorials blog has posted a series they've worked up to show bloggers out there running WordPress how to create a custom theme from scratch:

In this multi-part series I'll detail how to create and design a Wordpress theme from nothing more than your imagination using Photoshop, CSS, XHTML and PHP.

Here's the list so far:

• Part 1 - getting the tools and an overall layout idea
• Part 2 - splitting it up to make the layout parts
• Part 3 - converting the Photoshop template to XHTML
• Part 4 - cleaning up the XHTML and doing some styling with CSS
• Part 5 - how to preload some images with Javascript to make the page load faster
• Part 6 - creating the WordPress-specific markup
• Part 7 - working up the PHP functionality
• Part 8 - integrating PHP into the template
• Part 9 - marking up the "framework" of the site (header/footer/sidebar)
• Part 10 - adding additional files like a links page and changing the posting template
• Part 11 (?) - deploying the theme out to the public view

On PHPBuilder.com today there's a new tutorial posted showing how to combine the Javascript power of Prototype along side PHP's adaptability to create a simple, ajax-driven shopping cart for your site.

In the latest installment of this ongoing PHP series, I'll show you how to build a shopping cart using PHP, session handling, and the Prototype JavaScript library. The cart allows users to add and delete products from the cart, as well as change cart quantities. And of course, the interaction is seemingly instantaneous, allowing for the user to continue shopping without waiting for the page to reload.

They start from the ground up - making the database tables, inserting some data - before writing up the simple PHP class with methods like deleteFromCart and getCart. This lays the foundation for the next article in the series where they add in a splash of ajax to make it a bit more user-friendly.

Tony Freixas continues his introductory look at "booting" a PHP script with part two of his series (here's part one) looking at using libraries.

In the good old days, if you wanted to create re-usable code, you would create a library of related functions or objects. Now, the excitement is all around frameworks. Everyone has one. What is the difference between the two?

He compares a library and a framework, pointing out key differences like how they fit with the application (controlled by or controlling) and dependencies they require. He rounds out his boot sequence, adding a few new parts to the structure of his example application.

Padraic Brady has kicked off a new series of blog posts with part one posted today - a look at the creation of a sample Zend Framework blogging application.

Starting any new application is like walking into a shop and being dazzled by the displays. You want everything but finally realise you only have so much resources to spend. So you isolate the specifics you must have, and focus on those.

This first part focuses on the planning stages of the application. He works through the features he wants the blog to have and some of the external libraries he's going to rely on (things like PHPUnit and jQuery). His goal for the series and the application is to have something he can replace his current blog with and to provide readers a step by step detail of the progress along the way.

On the Zend Developer Zone, a new podcast (PHP Abstract) has been posted talking about the latest release of the Zend Framework - version 1.5. Wil Sinclair and Brad Cottell are the hosts.

Today we are going to talk to Wil Sinclair and Brad Cottel. Wil is the manager of the Advanced Technologies Group at Zend. We will be talking about the newly released Zend Framework 1.5.

In this first article of a new series on the IBM developerWorks site introduces you to their method for creating your own "on-demand video website" with PHP:

In Part 1 of a three-part series on creating an on-demand video site with PHP, we begin by looking at the different flavors of digital video and their particular nuances. When creating video for the Web, the overarching issue you need to keep in mind is whether you want your video to be small and easy to download or whether you want it to be the best quality possible.

They'll also show you how to convert the video into the Flash Video format to make it easy to pull into an in-page Flash player. You'll need to register or log in to get to the article.

Stefan Mischook has just posted a new video in his set of PHP-related presentations - part one of a look at setting up the MVC structure in a Zend Framework application.

This video is a little more basic than the previous Zend videos.

The video runs about twelve minutes long and covers the use of the Framework to post information back to a page and insert some of the information back into the database.

On the Developer Tutorials blog today, Akash Mehta has posted the second part of his look at the "ultimate web development environment", a continuation from this previous part.

Today I'm going to look at a local development server and its PHP configuration, as well as some of the IDEs/editors available for Linux, especially the cross-platform options.

Tools mentioned this time include things like a local development server (invaluable) some PHP configuration tips and the editors they mentioned, things like Aptana, Eclipse and Zend Studio.

On the Tiger Heron blog, there's a continuation of the series that Tony Freixas has been writing to following the beginning steps of working with PHP. First there was the download/install, then setting up a development environment. This time, he actually gets around to writing a bit of basic code.

Specifically, I will describe how I boot my PHP scripts and why I boot them the way I do. Part 1 shows how my requirements for code portability and maintainability influence the boot process. Part 2 will go into more detail about the specific steps executed by the boot code.

His basic task for the first example is to make a templating sort of system, calling a Navigation class to output links in list items. He outlines the goals of the project, what he's found for his current solution and some alternatives he's discovered along the way.
