Most people who have a website have probably seen a chart of their web traffic statistics at some point. What they may not know is how these charts where created dynamically using PHP.



Charts like the one above can be drawn using PHP code if your version of PHP has GD Library support (and it more than likely does.) The advantage of this, over static charts, is that you can change them just by changing the variables, so they can be created on the fly to fit any data instantly.
