PHP error handler. Converts all errors to logged exceptions. Warnings are displayed, errors are thrown.

function ChitinErrorHandler ($errno, $errstr, $errfile, $errline, $errcontext) {
	$e =  new ErrorException($errstr, 0, $errno, $errfile, $errline);

	switch ($errno) {

		case E_WARNING:
		case E_USER_NOTICE:
		case E_USER_WARNING:
			// Don't even 
			if ($_ENV['SERVER_ENV'] == 'production')
				break;
		
		// These are unworthy of throwing an exception - just send the alert
		if (ini_get('error_reporting') & $errno)
			echo "<pre class=\"error\">$e</pre>\n";
		break;
