Tutorial: Simple Bar Chart using PHP

In this small tutorial I will explain how I created simple bar chart using PHP. Maybe in future I will write more about charts and to expand this library. Tutorial is for beginners.  For image manipulation and processing we will use GD library which is by default come's with PHP distributions. You need to enable GD2 extension in PHP.ini.
