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.

A PHP script to handle the most common errors that may occur on a Web site. When an error occours you can configure the script to notify you by e-mail. To make this script work you have to edit the apache configuration file the "ErrorDocument" section, also ".htaccess" is required. All you have to do is create the html pages which you want to show instead of the standard ones and a file with the extension ".htaccess" and put the neccesary lines in it.

The way it works is providing several report formats of error catching: logging, display and redirection to a customizable error page. ErrorHandler captures the errors and captures (to a customized level) the context and variables surrounding the source of the error and neatly organizes them as a series of reports.
