An introduction to computer programming using PHP. Comprising

Drawing the French tricolour with PHP

You can create images using the PHP GD library. The first tutorial Flags looks at drawing flags of the world, from simple flags such as Libya to more complicated flags such as the Stars and Stripes of the USA. In GD you can use functions such as imagecolorexact and imagefilledrectangle to create simple images.

Notice that the white rectangle has top left corner at (50,0), the bottom right corner is at (100,100)

$white = imagecolorexact($g,255,255,255);
imagefilledrectangle($g,50,0,100,100,$white);
