• Still a lot of migrations toward 5.2.5 and 4.4.8

You can check out the details on these and other statistics (like PHP usage by country and version) the complete monthly stats and the evolution stats. Oh, and don't forget - Damien and crew are the ones supplying the latest edition of the elePHPants to the PHP community!

The Developer Tutorials blog has a recent post that talks about manipulating objects in PHP with the help of the iterators that the Standard PHP Library has to offer.

It's a generally accepted fact that more readable code is more maintainable and easier for other developers to pick up. [...] Today I'm going to take a look at object iteration, most commonly found in the Standard PHP Library, and explore using the Iterator interface to simplify looping.

The main part of the tutorial shows how to implement the Iterator interface of the SPL to create your own custom methods, theirs being a Database version with methodsfor rewinding, reading and getting the

The DevX.com site has posted an introductory guide to using cryptography in PHP, showing how to use the various packages the language has to offer.

Cryptography is just one piece of the security puzzle, along with SSL/TLS, certificates, digital signatures, and so on. This article explains how to use PHP to implement the most common cryptographic algorithms. In addition to describing PHP's default encryption functions, you'll see how to use a wide variety of cryptographic libraries and packages.

Eirik Hoem has pointed out an online tool a coworker shared with him to work with regular expressions for multiple languages.

A coworker of mine has been working on a ajax enabled regex tool which lets you evaluate regex expressions in several languages (including PHP PCRE and PHP POSIX) with instant results.

The tool lets you put in the string you want to match again and the pattern you want to match with. The results are automatically populated below it, making it easy to fine-tune your expression to only what you want.

Stuart Herbert has posted his review of a book from Packt Publishing covering one of the most popular PHP-based database administration packages out there, phpMyAdmin, "Mastering phpMyAdmin 2.11 for Effective MySQL Management".

Mastering phpMyAdmin 2.11 for Effective MySQL Management by Marc Delisle is the third edition of this book, and it follows the usual pattern of Packt Publishing books. The book has clearly defined objectives on the cover, and it follows a clear progression of its chosen subject from start to end. It is well presented, with a clear layout and clean page design that makes it easy to read.

Stuart gives a

On his blog today, Pierre-Alain Joye has posted about a TestFest call being made in the Munich area for participants wanting to help improve the PHP language.

Yet another PHP TestFest call, this time for the Munich area (and even for all Southern Germany). Johannes and I are trying to organize one or more TestFest days. No PHP internal knowledge is required (like C knowledges), all you need is willing to help to improve PHP and a good mood

You can find out more information on what the TestFest is on its page on the qa.php.net website and, if you're not in the southern Germany area and still want to participate, check out

Rob Allen has posted his review of another PHP-related book from Packt Publishing, "Object-oriented Programming with PHP5":

Packt Publishing recently sent me a couple of books to review, so let's start with Object-Oriented Programming with PHP5 by Hasin Hayder. According to the introduction, the book is intended for beginners to intermediate PHP5 programmers and the first chapter has a good introduction to what object oriented programming is and why you would want to use it.

He glosses over the first few chapters of the book (introductory stuff mostly) and points out three others specifically - Chapter 5 covering reflection and unit testing, Chapter 6 covering the SPL and Chapter 9 dealing with SimpleXML and DOM.

In many companies, business logic resides in Excel. This business logic is sometimes created by business analysts and sometimes by business users who want to automate parts of their everyday job using Excel. This same Excel-based business logic is often copied into an application (i.e. a website) and is maintained on 2 places: if the Excel logic changes, the application should also be modified.

Rob Allen has posted a review of the Packt Publishing book "Learning PHP Data Objects" over on his blog today:

Packt Publishing recently sent me a couple of books to review. This post is about the second one I received, Learning PHP Data Objects by Dennis Popel. I was excited to receive this book as PDO underlies a lot of the Zend_Db_Adapter objects that I use in my day to day programming. It seemed like a good idea that I should know more about it.

He provides some good detail of what the book covers (chapter by chapter) as well as a summary including his recommendation for who should use the book and how they can best enjoy its contents.

On the Zend Developer Zone there's a new tutorial (by Matthew Weier O'Phinney) covering the use of decorators with the Zend_Form component of the Zend Framework.

One point of flexibility [Zend_Form] offers has proved to be a pain point for many developers: decorators. This tutorial aims to shed some light on decorators, as well as provide strategies for creating your own decorators and combining them in creative ways to customize the output your forms generate.

Matthew starts with a little background behind the component to help you find your way around. Building on this, he shows how to use some standard output decorators and how to create decorators of your own. His example shows how to create a set of grouped checkboxes.

Andi Gutmans of Zend has posted about the next step in his personal growth on the internet - a personal site/blog of his own over at andigutmans.com.

For years I've wanted to run a personal Web site but never found the time to do it. A couple of weeks ago a few Zenders and I started leasing a dedicated server which gave us each a bit more hosting flexibility. Once we got the machine up and running I decided it was finally time
