Log watcher is a PHP class that polls log files and takes
newly added lines to send them to a given watcher email
address. Although this class can be used to poll any type
of log files, it was developed with the intention to
overcome a limitation of the PHP error trapping system
that is not able to capture certain types of errors during
script execution, like script parsing errors or form file
uploading failures. It is meant to be used from cron-like
task schedulers to poll log files regularly. The email
notification message can be composed from text
templates. The message delivery function can be replaced by custom functions like the urgent mail function that can be faster for delivering critical messages.
