Using PHP Error Handling

An all to common error on the web is broken links. You end up with broken links from other sites whenever you rearrange your site. People bookmark some page they like and come back 3 months later only to find a '404 Not Found', giving them no help whatsoever about where to start looking for the page you originally had on your site. Let's solve this, or atleast be friendly to your users and help them get back on track whenever they hit 'a 404'. You can even create a common page to report all errors you might encounter while rendering your pages.
