PHP est un langage de programmation interprété, c'est à dire que le fichier texte contenant le code PHP est analysé puis traité directement (pas de code compilé). Nous allons voir comment optimiser PHP pour tirer le maximum de performances.

we will explore different techniques for democratizing our design through the use of style sheet switching. By applying a different CSS file to a markup document, we can drastically change any or all aspects of its design—the layout, typography, or color palette. This technique may hold incredible appeal to designers because it exponentially decreases the amount of overhead required to redesign a site. But, as you’ll see, this technique can wield incredible benefits to our site’s users, allowing them fine-grained control over a page’s presentation and, in turn, better access to the content therein.

This article deals with the display of tree-structures that are driven by a database. There are actually a few approaches to transform a 2-dimensional structure into a tree, and it seems odd that most are unknown to many developers.

MVC implementation in PHP

In our struggle to reduce the number of steps site visitors must take to accomplish their goals, we face a number of challenges. One of them is to provide a good way for users to choose from a list of hierarchical elements. For example, a list that serves as a diner menu, offering a selection of drinks, main dishes, salads, and desserts.

In information management, persistence and availability are in constant tension. This tension has led to separate technologies for Uniform Resource Names (URNs) and Uniform Resource Locators (URLs). Meanwhile, Uniform Resource Identifiers (URIs) are designed to serve as both persistent names and available locations. This article explains how to use the current URI standards with XML technologies, gives a history of URNs and URLs, and provides a perspective on the tension between persistence and availability.

We have been well conditioned to recognize and delete the endless stream of spam, phishing attempts, Nigerian scams, and virus attacks we get every day in our inboxes. We have been so far behind for so long in the battle with computer security that we have almost forgotten some of the most basic insecurities that we put up with day after day.

Database management systems implement abstract concepts but do so on real hardware bound by real physical constraints. As a result, queries take time—sometimes an annoyingly long time. Find out how to minimize your wait in this sample chapter.

This tutorial explains the features and benefits of a Web format called RSS, and gives a brief technical overview of it.

Content, structure and presentation are now precisely defined, but I believe that the behaviour layer is too tight for javascript, javascript is not only about events, and separation is not good for the evolution of javascript. Modern javascript is in fact breaking the layer-model we thought was correct. I believe it’s perfectly logical to have presentational javascript which can go throughout structure and presentation.
