This script will allow you to display customizable error messages, and mail you when an error occurs with the user details (like IP number, user agent, etc.) and the page that user has requested.
This script will alert the webmaster quickly if an error occurs on a PHP Web page by emailing the person details of the error. This is very useful for Web sites with part-time webmasters and large ones where not every page can be tested by the webmaster.
404Handler will trap those dreaded "404 Not Found" errors on your site and email you the details of each 404. You can choose to receive email on one of three levels: no mail, mail only if the 404 was generated by a link on your own site, or mail warnings of all 404 errors regardless of where the link is located.
Small script that handles all 404 error reporting. Referring URL, missing file, date/time, and IP can be logged in a file, and the user may send the Webmaster an e-mail explaining the problem.
