Get flash to fully experience Pearltrees
PHP is a powerful scripting language that fits gracefully into HTML and puts the tools for creating dynamic websites in the hands of the people — even people like me who were too lazy to learn Perl scripting and other complicated backend hoodoo. This tutorial is for the person who understands HTML but doesn’t know much about PHP. One of PHP’s greatest attributes is that it’s a freely distributed open-source language, so there’s all kinds of excellent reference material about it out there, which means that once you understand the basics, it’s easy to find the materials that you need to push your skills.
