How to generate text representation of an image using PHP?

We will learn how to convert an image to its text representation using PHP that can be used in an html page (if any such requirement arises in your application or just for fun sake :) ).

1. Get the width and height of the image to be converted.
2. Loop through every pixel value in the image.
