TeeChart for PHP is an Object-Oriented Charting component library for PHP. The library is completely written in PHP and ready to be used in any PHP scripts. TeeChart for PHP is offered via two formats, the Free Open Source version and the Licensed Pro version. Both include the full source code meaning that no loaders have to be used in order to create a Graph on your servers. Most of the features are identical between versions; the significant exceptions being that only the licensed Pro version of the TeeChart for PHP library may be used in a commercial context and that standard support is only available for the licensed Pro version.
