When working with XML-based applications, developers often find themselves facing the requirement to generate XML-encoded data structures on the fly. Examples of this include an XML order template based on user input in a Web form, or an XML representation of a server request or client response based on run-time parameters.

You would learn basics of XML and how to format XML documents. Useful code snippets for your future programming.

XPath is a language that allows you to address parts of an XML document, making XSLT transformations practically necessary. It also makes it an invaluable tool for managing XML data in applications such as Web applications.

Sometimes you just need to know what country your site visitors are coming from—for example, if you’re trying to implement geo-targeted advertising. This article will show you how.

Article describing usage of geoip class with nice examples of code.

One of Yahoo’s performance rules says: Use cookie-free domains for static components. This is good because the server has no use for cookie information when serving a JPEG or another static component, so all this cookie information creates network traffic for no reason.

Like usually good article with some examples and code snippets.

- Which framework is the best of the three to you?
I know it depends on their use but I was just wondering

If you still does not decided witch one you should use maybe this Alex post would help you.

For any real application though, that won’t work and we require a “New User Registration’ system. That’s what we are going tot create in this post.

In this tutorial you would find code examples, good commented source. Looks like this tutorial is one of tutorial series. Great job from author.

here’s nothing quite like having a functioning application emerge out of the controlled chaos we know as The Development Process. In Part 8 of the ongoing saga describing how to build a real world blog application using the Zend Framework we finally reach the point at which we concentrate on blog entries. At the end of this Part, we will be able to create and edit entries in preparation for Part 9 when we will explore displaying them to the world!

In this part you would learn how to make blog entry editing controller, work with Zend_Form, how to filter entries with HTMLPurifier. Like usually  many code examples and new SVN repository.

Learn how to build Web services in PHP using the PHP Development Tools plug-in in Eclipse Europa. Become familiar with the PDT project, and learn how to create and deploy useful PHP projects, learn about the philosophy behind contract-first development, and understand the basic parts that make up a Web Services Description Language (WSDL) file.

In Good’s ebook is shown how to create web services (WSDL).

I have always had an issue with PHP Sessions. Albeit, a lot of my issues are now invalid. When they were first implemented, they had lots of issues. Then the $_SESSION variable came to exist and it was better. Then memcached came to exist and you could store sessions there. That was better. But, still, after all this time, there is one issue that still bugs me.

Looks like all my problems with session cookie diapered with Brian provided code snippet.
