NWS Public Alert Messenger PHP Script

It should be self maintaining or the log would grow continuously.
Maybe it could auto purge oldest alerts after x amount of alerts are built up.
The x amount of alerts to store could be a setting that can be changed.
Also the logging feature can be enabled or disabled with a setting.

Does this sound good?
I might not do this for a few days, I have programmed so many hours this week I feel tired.
Right now, I am working on two computers at once, and writing a seminar: Internet and Computer Safety - “How to stay clear of viruses, adware, spyware, spam, and scams when using the Internet”.
