Gtk2_ExceptionDump catches and displays common errors and warnings that can be produced in a PHP scripts: PHP errors, notices and warnings as well as PEAR Errors and uncaught exceptions. They are displayed in a Gtk2 window with a tree view, providing the error message and the backtrace with passed parameters.
The most easy thing to do is letting the class handle everything automatically. You can decide which errors should be catched: All, PHP errors, PEAR errors or uncaught exceptions. The following methods need to be called statically to set up error handling:
