PHP Web Watcher
By
James Wright

PHP Web Watcher will email the webmaster if the web site is down. I made Web Watcher for my company's web site. If my company's web site is down, I need to be contacted as soon as possible. PHP Web Watcher will check every 10 minutes to see if the web site is up or not. For security reasons, I disabled the email feature for the example. WARNING: If you post this script on your site, spammers can use it to send spam using your server.

EXAMPLE

No emails will be sent using the above example.
