DevShed continues their look at using polymorphism in an application with the latest part of the series - “Building Dynamic Web Pages with Polymorphism in PHP 5″.
In short, Polymorphism is a feature exposed by certain objects that belong to the same family, which eventually can behave differently, even when they’re using identical methods. Or more clearly, an object can be considered polymorphic when it’s capable of performing different actions by utilizing the same method.
This time they focus on web page development that uses this object-oriented practice. The create a WebPageElement that you can ID and class attributes on and use it to create HTML widgets and extend them to create Div and Link element.

The Zend Developer Zone continues their great series of security tips with two new posts - one talking about when to focus on security and the other about file uploads.
From the first, top 17:
Application security should not be a “when all else fails” situation. It’s not something you can “put in later”. As we’ve mentioned before, there is no single silver bullet to solve your application security issues. Security is something that should be rolling around in the back of your dead in the design phase, the coding phase, the testing phase, even after you’ve rolled your code into production.
And, from tip #18:
When you allow users to upload files, your system may be at risk. Always restrict the file types that you allow. Don’t rely on a blacklist approach. […] Be careful with file uploads and make sure you protect them with a whitelist policy instead. Make sure that the file that has been uploaded is of the type that you want to allow.

David Coallier points out a new feature of the main PEAR website (http://pear.php.net) - integration of the jQuery framework to help with the administration of a recent addition to the site, user comments.
http://pear.php.net is now using jQuery for some sections of the administration area in order to view user notes/comments and that I will be starting implementing more sections over the site within the next few weeks (Of course this will all be done once we have split the code completely into templates, views, controllers, MDB2 move, etc)
He also makes some comments about the number of Javascript frameworks out there and a mention of the roadmap for the rest of the features they plan to add to the PEAR site.
