<?php
// Define a custom error handler for more details
function detailed_err($errno, $errstr, $errfile, $errline, $errcontext) {
	// First of all, begin by noting that a fatal error occurred, and basic
	// details just like a normal error report:
	echo "<p>FATAL ERROR - {$errstr}</p>\n";
	
	// Now use debug_print_backtrace to give the function call list in
	// a compressed format easy for quick scanning:
	echo "<pre>\nFunction Call Tree:\n";
	debug_print_backtrace();
	
	// To finish off our 'extreme' debugging mode here, let's also give
	// a full backtrace dump, which will contain all variables that existed
	// and much much more.
	echo "\nFull Backtrace:\n";
	var_dump(debug_backtrace());
	
	// Close off that pre tag
	echo "</pre>\n";
	
	// That's it, time to make sure the script dies:
	die();
}

// Now go ahead and register this as the error handler:
set_error_handler('detailed_err', E_ERROR | E_USER_ERROR);
