By making all your web pages PHP pages from the start, you are basically leaving open the possibility of using PHP in your web pages at any time.

By his reasoning, it provides an "out" for you later on should you decide that a page needs to have some dynamic content thrown in there somewhere (without having to change the filename - bad for SEO, supposedly).

Scalable Vector Graphics (SVG) is an XML specification for producing vector-based graphic content that you can create, modify, and manipulate dynamically from programming languages. Here, you'll explore the most important techniques and libraries for integrating SVG with PHP to create diverse graphic contentâ€"from simple shapes to complex graphs.

They show a few different ways to get the job done including a straight 'echo' call with the output, sending a converted SVG document over with a PHP header or including another (or multiple) SVG documents into another and outputting them. They also talk about tools like the phpHtmlLib library, the PEAR::XML_SVG package and the PEAR::Image_Canvas package.

Well, first, what is an MPM? It stands for Multi-Processing Module. [...] The most commonly used threaded MPM is the Worker MPM. In this MPM, you have several processes that run multiple threads within it. This is the one I will be talking about.

He goes on to describe the "huge memory savings" that using the module got them - using the worker process to increase the child capacity of the Apache instance. He recommends keeping it simple when compiling a server to work with the worker functionality and mentions how it can also help with serving static pages right along side the dynamic ones (without a second server!).

Without a little background in programming languages or computer science in general, it's entirely possible that typing systems are not something that have crossed your mind. I thought I'd take a blog entry to share some of my thoughts on how it’s affecting the creation and evolution of languages.

He walks through history a bit, mentioning C, Java, Python and PHP and how they differ in their default type handling. He especially focuses on the "blurred line" between strong and weak typing and how some if offers special features to the language that uses the method.
