Rui CarmoThis is the PHP version of netgrowl, which took me all of half an hour to do. With it, you can have your PHP-based web servers notify you instantly of any strange occurrences.
Like the rest of the Growl code, this is under a BSD-style license.
The overhead involved in creating an UDP socket and sending a single packet is negigible, so this can be used without any performance concerns. Just be sure to prevent excessive notifications - you don't want to get notified about every single web page hit, now do you?
