TeeChart for PHP available with 100% PHP sourcecode. It supports PHP5 and above. It can be integrated as a palette component into the Delphi for PHP programming environment as used on others by creating the components at runtime. The first version offers 17 Chart styles ( in 2D and 3D plus multiple combinations), 11 mathematical functions and some Chart tools components for additional functionality. We're still working on it, adding more Chart styles and features for the next releases.
Please take a look, the evaluation version includes working examples for most Chart types. You'll see how easy it is to code TeeChart and how you can improve department development productivity.
