Learning PHP: Get Started Using PHP

This PHP tutorial will guide you through the process of learning and using PHP, preparing you with some fundamental knowledge to get you started in the right path. We will talk about the history of PHP, create a local development environment (so that you won’t need a web server) and create a basic PHP script while discussing common beginner PHP gotchas along the way.

Introduction

In the beginning, there was nothing. Well, there were static web pages that had to be edited manually. That was a pain. And it didn’t do anything other than display text and images on a web page.
With the introduction of PHP/FI (Personal Homepage Tools) in 1995, everything changed. It became possible to create dynamic web applications that generated content on-the-fly and allowed users to interact with the once static web pages.
When Rasmus Lerdorf, the creator of PHP/FI, decided to release the source code of his project, the development went even faster.
Andi Gutmans and Zeev Suraski joined the project in 1997 and started working on PHP 3.0 as the official successor of PHP/FI. The development of PHP/FI was mostly halted. PHP 3.0 (which is a recursive acronym for PHP: Hypertext Preprocessor) was officially released in June 1998.
Shortly after the release, Andi and Zeev were already working on a rewrite of PHP’s core. It was finished in mid-1999 and the new engine, dubbed Zend Engine (comprised of parts of their first names, Zeev and Andi), was a huge success.
PHP 4.0, based on the new Zend engine, was officially released in May 2000.
After four long years, PHP 5.0 was released introducing a new object model and dozens of other new features. In 2010, PHP 5.3.1 is the latest stable release.

Be Healthy: Simple Exercises for Freelancers

Sitting in a chair working for most of the day is never healthy. If you’re a freelancer, it means you’re pretty much glued to your chair since there is no getting up and going over to a colleague’s desk to talk about a project, walk to a meeting, elevator or across the street for lunch.
Ignoring the fact that gluing your behind to your work place most often than not, piles on the pounds but also leads to something far more unhealthy – inactivity.
If you have recurring back aches, stiff neck and creaking joints then your body needs to start moving.
Here are a few simple stretching exercises which won’t reduce your weight, but will keep your body active and blood circulating!
Important note: All these stretching exercises should be done regularly and moderately in sets of 5.

Using Chess For Success in Web Design

The business of building websites is one of constant change, adaptation and strategy. The way designers and developers build websites is often informed by the methods of others and their own trial and error. In light of this, we can draw a number of parallels — some philosophical, to a certain extent — between Web professionals and one of the oldest and most popular board games of all time (counting traditional and digital games). This game is chess.
