These tools can be used to speed up the process of developing PHP apps. I use them in conjunction with my
very lightweight PHP 'framework', however only the database tool is actually dependant on that. (It needs corelib/dataaccess.php to
use MySQL or corelib/dataaccess_lite.php to use SQLite; the rest of NBFramework is optional.)

OK, this one's not for PHP - a tiny language that is (IMHO) easier than setting up the data directly for Gantt charts. The actual charts are produces using SVGGraph.

A simple one file app with help, examples and output, but no saving of user files. Basically the model for a minimal online tool.
