kreXX is a php debugger, which displays debug information about objects and variables in it's own draggable debug output.
It is actually a fork of Krumo which can be found here:
http://krumo.sourceforge.net/
We have used Krumo for some time in our projects, but added more features as we needed them. And so kreXX was created.
Usage:
After installation just use
krexx($object);

Small PHP library to view (1) all the executed MYSQL queries and their result (read data, affected rows, errors and their reason) and (2) all received GET and POST variables. This library makes it very fast to find why queries did not work as expected.
