In the real world some bugs may still escape when you ship the code to production. So you will want to know of any notices caused by missed bugs, so you can fixed them sooner rather than later. What you should not do in production is to show error messages on the page. I recommend the following php.ini settings: http://www.phpclasses.org/browse/file/5051.html What I do is to make PHP generate an error log and then can keep monitoring it. If there are any log lines get added, the monitoring script that is run regularly from cron, sends the added lines by urgent mail to me so I can act promptly and fix any bugs before it is to late to avoid major damage. I use this class to watch PHP error log. http://www.phpclasses.org/logwatcher For sending really urgent mail, I use this class. It comes with a wrapper function named urgent_mail(). It emulates the mail() function but it attempts to inject the message directly in recipient SMTP server, thus bypassing the local mail server, which is a good thing as the local mail server may be too busy or not working at all (think of a disk full or exhausted RAM). http://www.phpclasses.org/mimemessage I lost count of how many hours these small scripts save me of major headaches and greater damages that could have been caused by often subtil bugs. -- Regards, Manuel Lemos Metastorage - Data object relational mapping layer generator http://www.metastorage.net/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
