Many PHP developers use print_r() & var_dump() for debugging which output hard to read/unformatted results.

Krumo is a replacement for these functions which can display structured information about any PHP variable.

Once Krumo is ran, the output is displayed in a collapsible DHTML tree built around the structure of the dumped PHP variable.

Also, it speeds up the debugging process by the ability of turning it "off" rather than disabling every dumping route inside the code.

Krumo runs on PHP 5 & to see how useful it can be, check the examples.
