PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML, as a server-side include language. It is frequently used in technical communication practice in conjunction with databases, as in many content management systems.
Agility includes effective, that is, rapid and adaptive, response to change. This requires effective communication among all of the stakeholders. Stakeholders are those who are going to benefit from the project in some form or another. The key stakeholders of the project include the developers and the users. Leaders of the customer organization, as well as the leaders of the software development organizations, are also among the stakeholders.
Ces termes affreux sont très à la mode dans le milieu du développement de solutions/sites Internet ou Intranet. On ne peut pas discuter 2 minutes avec un développeur sans qu'il en prononce un ou deux (voire tous si il est dans la catégorie 'Développeur souffrant de gros problèmes de communication avec les non-développeurs' !). Pour dire la vérité, il est même parfois difficile de s'y retrouver quand on est de la partie... C'est pour cela que nous allons essayer ici de définir simplement ces termes et de les regrouper par grandes familles. Ces termes caractérisent les différents langages que l'on peut utiliser pour le développement d'applications web. Ils se séparent en deux grandes familles selon que les scripts (programmes) s'exécutent sur le serveur ou sur le client.
Ordered lists are boring! Sure you can apply background images and do quite a bit of sprucing up to a regular ordered list, but you just don’t get enough control over the number itself. Here is an example where you ditch the traditional ordered list and create your own!
The humble contact form: It's the cornerstone of nearly every website, from the humble personal blog right up to the corporate megasite--and a billion small business sites in-between. In the early years of operating a website, we were happy to put our shiny new email address out there for anyone to mailto, but the rise of the spammer has made us justifiably wary of publicizing our contact details--enter the contact form.
Test-driven development and unit tests are the latest way to make sure your code is behaving as you expect through changes and refactoring. Find out how to unit test your PHP code at the module, database, and user interface (UI) level.
Picasa Web Albums offers Web application developers a REST-based Data API to manipulate the photos and albums stored on its servers. PHP's SimpleXML extension and Zend's GData Library are ideal to process the XML feeds generated by this API so you can customize PHP photo management and photo sharing applications. In this article, meet the Picasa Web Albums Data API and see how you can use it to retrieve photos and photo metadata; add, modify and delete photos; and perform keyword searches of Picasa's user-generated content.
Single quote, double quote, or no quote? This seemingly simple question is often asked by those new to PHP. Suprisingly, however, some of those who claimed to be PHP programmer also can't tell the difference. It's very simple, really.
PHP is one of the most widely used open-source server-side scripting languages that exist today. With over 20 million indexed domains using PHP, including major websites like Facebook, Digg and WordPress, there are good reasons why many Web developers prefer it to other server-side scripting languages, such as Python and Ruby. This post presents 50 useful PHP tools that can significantly improve your programming workflow. Among other things, you’ll find a plethora of libraries and classes that aid in debugging, testing, profiling and code-authoring in PHP.
Paul looks at how PHP, GIMP, or Generator can be used to churn out up-to-the-second charts and graphs, change your site's look and feel on demand, display newly created passwords as bot-defying GIFs, and more.
Classes add a lot of functionality to your code and help to stop you repeating yourself over and over again as you might in conventional code. With classes and functions you’ll be able to make generic scripts that you can simply call when you need them. Not only this but classes make your coding a lot more tidy, so you can usually find everything you’re looking for. When you know how to use them they can really speed up the speed at which you’re working.
When you are creating a web application forms and data should be held strictly seperate. In the PHP community this rule is ignored and PHP itself is being abused. Template and framework system developers have made it more commonplace. CMS developers seem to have forgotten that under no circumstances should the code used to display forms be allowed to process the data involved. Here's why not and the solution.
According to Netcraft, PHP overtook Microsoft's ASP as the most popular web scripting language back in the spring of 2002. And PHP has continued its explosive growth ever since. Today, when the Apache web server powers nearly 70% of all sites on the Internet and its closest competitor, Microsoft's IIS, has a market share of just over 20%, PHP is far and away the most widely used server-side scripting language. Just what is it that makes PHP so popular?
PHP can do a lot for your Web operation. You can generate nice-looking printable receipts, invoices, and brochures. Disc-Cover has a test site that looks up info about a CD automatically and then generates a PDF label for the CD box that you can print, cut out, and use. And there are literally one billion other possible uses for dynamically generated PDFs.
In this article we'll build a simple, template-driven site that separates style, content, and structure in your website. We'll create a cross-browser stylesheet switcher that remembers the user's preferences, touching on PHP variables, cookies, if statements, and including pages with require_once.
For many PHP programmers, object-oriented programming is a frightening concept, full of complicated syntax and other roadblocks. As detailed in my book, Pro PHP and jQuery, you’ll learn the concepts behind object-oriented programming (OOP), a style of coding in which related actions are grouped into classes to aid in creating more-compact, effective code.
PHP is an interpreted language. This means that each time a PHP generated page is requested, the server must read in the various files needed and "compile" them into something the machine can understand (opcode). A typical Drupal page requires more than a dozen of these bits of code be compiled. Opcode cache mechanisms preserve this generated code in cache so that it need only be generated a single time to server hundreds or millions of subsequent requests. Enabling opcode cache will reduce the time it takes to generate a page by up to 90%.
MySQL combined with PHP is a powerful tool. However, most beginners won’t know where to start, on how to extract the data from their databases, or what have you. There is just about 50 MySQL functions in PHP, all used to help you accomplish what you need with PHP. However, you’re probably not going to use them all, and below I’ll explain the key features.
This article demonstrates several ways to create configurable PHP applications. It also discusses the ideal configuration points in an application, and finding the balance point between an application that is too configurable and one that is too closed.
With the rise of Ruby on Rails and the concept of MVC (Model – View – Controller) architecture, many developers began to create helper libraries for PHP too, which are collectively called frameworks. There are numerous advantages of using a framework.
