Treating Warnings as Errors
I have a php application that I have just re-factored. Unfortunately it spewing out warnings like:
Warning: preg_match() expects parameter 2 to be string, object given in /home/yacoby/dev/netbeans/php/Zend/Db/Select.php on line 776
Which is impossible (or very hard work) to work out the issue as I don't have a callstack so can't tell which parts of my code are causing the warning and there is a lot of code.
I need a method to either treat warnings like errors (In that the application dies and prints the stacktrace) or I need the stacktrace to be shown when printing errors. Is there a method to do this?

See example #1 at http://www.php.net/manual/en/class.errorexception.php
<?php
function exception_error_handler($errno, $errstr, $errfile, $errline ) {
throw new ErrorException($errstr, $errno, 0, $errfile, $errline);
}
set_error_handler("exception_error_handler");
/* Trigger exception */
strpos();
?>
