John,
If you use a lot of functions (like with OOP) you may like to print a
backtrace. For this you can write a simple error handling function, see
http://www.php.net/manual/en/function.set-error-handler.php, that calls
debug_print_backtrace() (this function is php5 only, but it is also
available in http://pear.php.net/package/PHP_Compat ).
Greetings,
Henk Verhoeven,
www.phppeanuts.org (framework, includes error handler (prints a
backtrace) and unit testing tool)
