There has been a lot of talk over the past several years about the difference between performance and scalability. Never mind that the difference between the two will probably not really affect most developers. Never mind that the “difference between performance and scalability” argument is often used when someone’s code performs poorly and their best argument is “Yeah, but my code scales”. Yeah, sure it does. […]

The Scalable Vector Graphics (SVG) specification provides a way to programmatically generate images using vector paths expressed in XML. This makes it ideal for generating images that need to be scaled to different resolutions without losing fidelity. A common requirement in Web applications is to dynamically generate charts and graphs from numerical data. If these graphs are expressed using SVG, they can be blown up to different sizes without any deterioration in quality, and they are also typically smaller in size as compared to their GIF or JPEG counterparts. With this in mind, this article examines various open source PHP libraries that allow you to add SVG charting capabilities to your PHP application. […]

In the previous segment of this article, I introduced you to the Zend_Paginator class, which provides a flexible API for paginating any data collection, whether it is expressed as an array or a database result set. However, Zend_Paginator isn’t the only game in town. There are a number of other open-source PHP pagination widgets, which can be used as an alternative to Zend_Paginator. […]

This article will introduce you to one component that helps you solve the problem of presenting large data sets in a manageable fashion, Zend_Paginator, which is a part of the Zend Framework. However, open source is all about choice and so, a followup article will also discuss two other popular components, PEAR Pager and Doctrine Pager. Come on in, and let’s get started. […]

Like most developers, I've known for a while that PHP comes with GD support for basic image generation and processing tasks, and I've even used it on occasion to dynamically create images. However, what I didn't know was that, hidden in PECL, is an extension to the GraphicsMagick library, which allows for all kinds of sophisticated image operations and effects. In this article, I'll introduce you to ext/gmagick, showing you some of the cool things it can do for you (and your images). […]
