Smashing Magazine has posted a huge set of resources for the WordPress users out there - a toolbox containing links to tutorials and tips and tricks on various parts of the blogging tool.

With all of the WordPress development that is going on, there is a need for an organized collection of resources to educate, inspire and equip developers to improve the quality and efficiency of their work. This post provides all kinds of WordPress-related resources to do just that.

They've broken it up into a two categories - Helpful Resources and WordPress Tutorials - with topics ranging from working with comments and navigation menus to making your own WordPress theme from scratch.

With PHP4 out of the way, it's time to make way for PHP5. To get the ball rolling, Gennady Feldman has posted some links to PHP5 resources that can get you on your way.

After posting previous item on the end of PHP4 I thought it would be beneficial to put up a number of pointers for those who are still using PHP4 and are looking for information that will ease the pain of migration to PHP5.

Links include:

• http://www.php5.org/
• Why are you not using PHP 5
• Migration to PHP5

On the PHP::Impact blog today Federico points out five articles that can help you learn more about the Standard PHP Library, specifically in dealing with iterators.

When PHP 5 was initially released, it included a strong sense of standardization introduced in the core package. This can be a real time saver when common programming issues must be solved through proven, standard solutions. That's precisely the case with iterators, since the SPL package includes many predefined iterating classes that can be used for traversing different data structures, without having to reinvent the wheel over and over again.

The links include this article on phpro.org and this one on Zend's own site.

On the C7Y website, a new tutorial has been posted from Nate Abele (following his previous CakePHP-related article) covering the use of the framework to create a REST web service and manage resources inside of it.

We're going to take these concepts [from the previous article] further and add a new one: REST. In the course of this series so far, we've only been discussing how to use the Router to examine and act on different parts of a URL.

He gives a list of possible headers that could come from a client (like Accept-Charset or Content-Type) and how these can be directly pulled in to the CakePHP routing system. A few extra bits of code later and your app can be mapping requests directly to the controllers for the actions the user's requesting. All that's left is to serialize the results back into XML to echo out.

PageChain.net has posted a list of some "great places to go to" to learn PHP right now - some resources out on the web that can help you get started, provide examples and give you community to support you in your development.

Here are some resources to help you not only learn PHP, but also reference PHP information should you ever need it. This list isn't exhaustive, however, it should provide you with a lot of help when you need your PHP fix.

Some of the sites included in their list include:

• W3Schools PHP Tutorials
• Good PHP Tutorials
• PHPFreaks
• ONLamp

A little bit back Akash Mehta posted a list of seven sites he thought could make you a better PHP programmer for reading and keeping track of:

Developing in PHP isn't a textbook science. There's skill to it, and that skill comes from experience. Now, you could try your hand at every single PHP development challenge out there, or you could learn from the experiences of others, widely published on the web in blogs and developer portals.

Included in the list are sites like php|architect's C7Y site, Planet PHP and the the Zend Developer Zone (oh yeah, PHPDeveloper.org made the list too!)

Raphael Stolt, in working on his component for the Zend Framework (based on the PHP_CodeSniffer PEAR package), pulled together all of the information Zend provides about their coding standards into one place.

Before jumping into the development of a Zend Framework coding standard for the PHP_CodeSniffer Pear package, I spent some time revisiting and compiling the available Zend Framework coding standards into a handy one-paged Pdf document.

You can download the file here or, if you want something a bit more "spread out", check out the coding standards on the Zend Framework website.

On the Zend Developer Zone, ahamedjais has written up a tutorial that talks to the reader about the creation of an example PHP desktop application via PHP-GTK.

We have been creating web-applications using PHP since it came into existence, now we can also develop Desktop or Stand alone Applications with PHP-GTK. [...] Thanks to PHP-GTK, we can now build cross platform windowed applications with PHP as well.

He starts off by describing what PHP-GTK is and the essentials (like where to get it and how to test to see if your installation is working with some sample code). He also includes links to more resources about PHP-GTK including a PHP-GTK cookbook and a page describing all of the base GTK classes.

Nessa has set up a post in an effort to help budding PHP developers out there with some of the most common problems they might come across in their work and how to handle them a bit more gracefully with error handling:

I'm going back to the basics here, you know, when you wrote your first PHP script and saw an ugly-ass error message pop up on your screen? Error messages are the best tool a programmer has.

She talks about how to set up the error reporting first, making sure that you're getting things up and useful. From there she describes some of the common errors that you might see including:

• Parse errors
• MySQL Result source errors
• Stream errors
• Max Execution Time errors

Check out the rest of the post for more types.

In a new post Gennady Feldman has listed out some beginner resources to help those just getting into PHP:

I know that some of my last blog entries were a bit too technical for the web designers who are just starting out and curious about using PHP for their website. I thought I'd do a blog post with links for the newbies who are just starting out and making their first steps in PHP.

He points out the videos on the KillerPHP.com website, links to the PHP manual and the PEAR and PECL home pages.
