Re: Log observers

I had a similar problem but I discovered that the pattern was implemented in the Horde project so used that as a guideline. I here are two chunks of code I have be working on: <?php include_once 'Log.php'; include_once "Log/observer.php"; include_once "observer_fatconnect.php"; /** * @package Connect */ define('APPLICATION_LOG_DEFAULT_PRIORITY', LOG_INFO); define('APPLICATION_LOG_MAX_PRIORITY', LOG_DEBUG); define('APPLICATION_LOG_EMAIL', LOG_ERR); /* ApplicationLog::logMessage($entry, __CLASS__, __LINE__, $level); */ class ApplicationLog { function logMessage($message, $file, $line, $priority = APPLICATION_LOG_DEFAULT_PRIORITY, $email = APPLICATION_LOG_EMAIL)

    {
        static $logger;

        if (!isset($logger)) {

            $conf = array('mode' => 0600 ,'timeFormat' => '%x %X');
            $logger = Log::singleton ('syslog', 'Syslog', 'FatConnect', $conf, APPLICATION_LOG_MAX_PRIORITY);

            //set the lowest level we want to be emailed about
            $observer = new Log_observer_fatconnect ($email);
            $logger->attach($observer);

            if (!$logger || !is_object($logger) || !is_subclass_of($logger, 'log')) {
                echo "No logger \n";
                if (PEAR::isError($logger)) {
                    echo "Logger error \n";
                } else {
                    echo "Logger error and ApplicationLog can't log it \n";
                }
            }
        }

        $message = $message . ' [on line ' . $line . ' of "' . $file . '"]';
        $logger->log($message, $priority);

        return true;
    }

} ?> <?php define('LOG_OBSERVER_EMAIL', 'wolstena@sfu.ca'); /** * The Log_observer:: class implements the Observer end of a Subject-Observer * pattern for watching log activity and taking actions on exceptional events. * * @author Paul Wolstenholme <wolstena@sfu.ca> * @package Connection */ class Log_observer_fatconnect extends Log_observer {

    /**
     *
     * @param array     $event      A hash describing the log event.
     */
    function notify($event)
    {
        $subject = "[FatPort]" . $event['message'];
        $body = "An error of priority: " . $event['priority'] . " has occured. \n\n";
        $body .= "Where:
            LOG_EMERG =    0
            LOG_ALERT =    1
            LOG_CRIT =     2
            LOG_ERR =      3
            LOG_WARNING =  4
            LOG_NOTICE =   5
            LOG_INFO =     6
            LOG_DEBUG =    7\n
        ";
        $body .= "The error message returned is: " . $event['message'] . ".\n\n Better get on it :-)";
        $mail = mail(LOG_OBSERVER_EMAIL, $subject, $body);

        if (!$mail)
        {
            trigger_error('Log email notification routine has failed', E_USER_WARNING);
        }
    }

Hi, I'm currently logging words that are entered in to a search box on my web page. At the same time as logging these words to a text file on the server I would like to inform somebody via email. Is this possible via the observer mechanism? The documentation doesn't really expain what it is and assumes you know already it seems! I can't find any sort of in-depth examples of using the PEAR::Log either. Help help help much appreciated on this. Thanks. -- Mike Carter [Senior Web Developer] Personal Medical Advisor Limited.
