This article describes the steps to create a custom PHP extension DLL for the Windows platform. The Zend API documentation that comes with PHP 5 on Windows (see php_manual_en.chm) does a good job explaining how to write extension methods, parse method parameters, and return values. But there is not currently a good step-by-step tutorial on how to get your first extension project up and running on Windows. The aim of this article is to fill that gap.PrerequisitesVisual Studio 2005You can alternately use the free Visual C++ Express Edition or the VC++ 8 compiler in the Windows SDK v6.0 if youâ�...

PHP's meaning of overloading is different than Java's. In PHP, overloading means that you are able to add object members at runtime, by implementing some of the __magic methods, like __get, __set, __call, __callStatic. You load objects with new members. Overloading in PHP provides means to dynamically "create" properties and methods. These dynamic entities are processed via magic methods one can establish in a class for various action types.Some example:class Foo{    public function __call($method, $args)    {        echo "Called method $method";&n...

We've always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we're performance wonks (guilty!), but because we think speed is a competitive advantage. There's plenty of experimental data proving that the slower your website loads and displays, the less people will use it.[Google found that] the page with 10 results took 0.4 seconds to generate. The page with 30 results took 0.9 seconds. Half a second delay caused a 20% drop in traffic. Half a second delay killed user satisfaction.In A/B tests, [Amazon] tried delaying the page in increments of 100 mill...

With the release of the iPad, HTML5 technology has recently come into the spotlight.  The format that will likely kill Adobe’s Flash is a lot of fun to use, but we’ve  not seen much of it yet.The good news is that you don’t have to wait until the iPad is in your hands to see what HTML5 can do.  If you have a compatible browser, there are already a wealth of sites that show off the capabilities.First, make sure that you have a browser that is capable of rendering HTML5 content. At the moment, Google’s Chrome is king in this department.  So for the...

HTML5 is generating all kinds of buzz these days. Some of the buzz is about HTML5 being a replacement for Adobe’s Flash. I don’t think it’s there yet but it’s certainly on the way to changing the way content is presented on the web. This is a description of a very simple animation in an HTML5 canvas element. It is coded for readability and not for optimized operation.We’ll add a canvas element to a web page and then use javascript to draw on it. We will redraw it all every 10 milliseconds with minor changes to create the magical illusion of animation. Using j...

You’ve probably been hearing a lot lately about how Flash is a dying technology and how it’ll soon be replaced by HTML5. Personally, I think that it will slowly replace Flash for some things, but Flash will always have a place, especially for developing complex games and rich internet applications. If you’ve yet to see what HTML5 can do, I’ve rounded up 10 demos that show off some of its capabilities.So what do you think – will HTML5 replace Flash?Canvas Minimal Particle AnimationCanvasMolFlickr and Canvas in 3DCloth SimulationetchaPhysicsGoogle Images Gift B...

A comparison of streaming video via the Adobe Flash and HTML5 formats with numerous different browsers on both Mac and Windows produced wildly different results based on the operating system and browser, making neither a clear winner.The test, from Streaming Learning Center, was conducted in response to recent comments alleged to have been said by Apple co-founder Steve Jobs, in which he reportedly called Flash a "CPU hog." While the test found that HTML5 is significantly more efficient than Flash on the Mac when running the Safari Web browser, those same advantages do not exist on other Mac b...
