pChart 1 for PHP 5

Why?

pChart is a great charting library for PHP. The original library (http://pchart.sourceforge.net/) was written in PHP4 and is no longer maintained. It's author created a new version called pChart 2 that is available at http://www.pChart.net

Unfortunately his licesing terms lined out at http://www.pchart.net/license are confusing:

If your application is not a commercial one (eg: you make no money by redistributing it) then the GNU GPLv3 license (General Public License) applies.

This is contradicting itself. The exclusion of commercial appliance is in direct violation with the GPL and thus renders it invalid. This standard copyright applies and the library can not be used in any Open Source program.

The author was informed about these invalid license terms in November 2011, but hasn't changed anything.

This leaves only the old, GPL Version 2 licensed version 1 of pChart. However, it has not been updated in a long time and it's compatibility with PHP 5 will soon be lost because of new language features (namely constuctors can no longer be the class name as of PHP 5.3.3)

This project aims to update the library to modern PHP5. It will not retain backward compatibility with the old API (though it will not be changed unnecessarily)

Goals

The goal of this project is:

  • Update pChart to use PHP 5 object-oriented language features
  • Fix bugs
  • Refactor as needed
  • Add proper docblocks to all functions (and there's a lot of them)
  • Rename some functions (it seems the original author's native language was not english)
  • Have clear a license

Status

This project was started by github user aweiland at https://github.com/aweiland/pChart-php5 but all the API documentation and continuous integration server seems to be down. Development was picked up by github users timmartin and sebix but stopped again.

The current repository at https://github.com/splitbrain/pChart is the most recent pickup, but I'd be happy to give development over to whoever wants to drive this project forward.

Todo

  • unit tests are failing currently but I'm not sure that comparing md5 sums of action logs is the right way to test anyway
  • the example files are probably the best way to really test the library for break/non-break state - these should be integrated into the test suite
  • the example files 15 to 29 are currently broken, probably just because of API changes not real bugs
  • the code needs more cleanup and most importantly useful doc comments to auto create a usable API documentation
Something went wrong with that request. Please try again.
