Php introduction

Overview
This PHP course designed to enable web developers and others with limited programming experience to build dynamic web sites using the PHP programming language. Since PHP is such a rich and task-specific language, the course covers the most important range of functions in depth, and equips delegates to understand the remaining less essential aspects. This 3 day course also handles such issues as cookies, sessions and database handling in a MySQL environment..

Prerequisites
Delegates should have some knowledge of web development and programming.
