How to do with display driver of PEAR::Log

I've used recently the display driver of Log package and i discovered something strange. Perharps i did it wrong, tell me if i missed something. my need: I want to display on browser screen a message with context (filename and line) in bold face. In the core of message i used html tags <b> and </b> to do it . it's not a really real case, but here are the code i used to produce such case: <?php require_once 'Log.php'; $logger = &Log::singleton('display'); $context = array('file' => __FILE__, 'line' => __LINE__); $message = 'invalid input'; $message .= ' in <b>' . $context['file'] . '</b> on line <b>' . $context['line'] . '</b>'; $logger->crit($message); ?> I expected to have Critical: invalid input in logger.php on line 6 and got only : Critical: invalid input in <b>logger.php</b> on line <b>6</b> Is it a wanted behaviour ? i noticed that line 98 of Log::display driver (version 1.8.4) has a htmlspecialchars() function $Header: /repository/pear/Log/Log/display.php,v 1.5 2004/01/19 08:02:40 jon Exp $ Laurent Laville ----------------------- PHP For Ever http://pear.php.net/user/farell
