DevShed: Creating AJAX Requester Objects with Abstract Factory Classes in PHP 5 [2007-01-31 19:33:51] DevShed has posted the second installment of their look at the Abstract Factory pattern in a new tutorial - "Creating AJAX Requester Objects with Abstract Factory Classes in PHP 5". In this second article of the series, I'm going to demonstrate how to apply the abstract factory pattern to create diverse AJAX HTTP requester objects, which can be used in distinct contexts. They work through Ajax development, creating the requestor objects for it, integrating it into the Abstract Factory pattern, and showing it in action - sending a simple message back to the calling script.

Soledad Pendaes' Blog: PHP will never have a (real) Rails-like framework [2007-01-31 19:32:21] Well, according to Soledad Pendaes, PHP will never have a (real) Rails-like framework because of some of the limitations with objects inherent to the language. I know the title is harsh but it's so true. At least it is according to nowadays php's implementation of classes and objects, which do not permit to "reopen" and add or redefine new methods to an existing class definition, which is the basis upon Rails (and I presume lots more of applications and frameworks) is built.

DotVoid.com:Parsing the user agent string using PHP [2007-01-29 19:08:47] On the Dotvoid.com blog today, there's a new post that shares some handy code to parse out information from the incoming user agent string for the visitors for your site. Recently I experimented a bit with an Apache log file analyzer written in PHP. It's not all that difficult were it not for trying to parse the browser, or user agent, string. [...] For my purposes I don't care much for the operating system details. This is the result so far. I'm still not very satisfied but I thought maybe other people might be interested and maybe help out. He provides the code in the format of an encapsulated PHP function that returns the product they're using, the version number of the browser and other various comments.

Ryan Malesevich's Blog: More Thoughts on Wordpress 2.1 [2007-01-29 19:04:24] On his blog today, Ryan Malesevich has posted two items about his recent experiences with the latest version of WordPress (2.1). One of the reasons was I wanted to upgrade Wordpress to 2.1 and I knew that it could take a while. I wanted to make sure there were no problems with plugins etc. But I've upgraded, and I would say that I haven't run into any troubles. Everything appears to work as it should. He follows this up with some initial impressions of the new version, including the image upload system and the auto-save functionality (to ensure the least amount of data loss, just in case).

Jonathan Snook's Blog: Review: PHP Solutions [2007-01-29 19:02:50] Jonathan Snook has posted a review of a book offered by the Friends of Ed publishing company - PHP Solutions: Dynamic Web Design Made Easy by David Powers. The folks at Friend of Ed were kind enough to send me a copy of PHP Solutions, by David Powers. This book is solely intended for someone who hasn't used PHP before but approaches it in a way that is different than most books I've seen. Jonathan talks about the contents of the book (installation, the basics, working with images, etc) and mentions what he liked about the book - mostly its forward-thinking approach including a look at PHP6 and a more well-rounded approach than just the traditional "put it in the database" ideas.

Sara Golemon's: You're being lied to [2007-01-29 19:01:14] If you think you know what's going on behind the scenes when you're working with objects in PHP5 - you're wrong. You're even being lied to, according to Sara Golemon's latest entry: If you're among the crowd who have migrated an OOP based application from PHP4 to PHP5, then I'm sure you've heard the expression "Objects are copied by reference by default in PHP5". Whoever told you that, was lying. As she explains, the truth is more that they behave that way, not that they are actually like that. She talks about what objects actually are and how things are handled differently from PHP4 to PHP5. She also "lies" a little also about the "copying" part, and explains the internal structure of a variable to show why. She also includes a bit on why referencing variables when it's not really a must is a bad idea - the main idea of it being a waste of space and memory in the application.
