For the most of the PHP scripter which are using preg_match or preg_replace frequently is the function preg_match_all a smaller advantage, but for all others it’s maybe hard to understand.

While reading some secrets about link building techniques I stumbled over the squidoo community. Like on other websites like mySpace it’s possible to create your personal page (a lens) and you can add there content like news, RSS feeds, links and of course your own content like text and images. The one thing what was new to me is that you can earn money with your lens; they have a kind of profit sharing. There are already Google AdSense ads between your content blocks and it’s allowed to add additional advertisements (for example banners) on your lens page and if your lens has a lot of traffic, you earn some money (don’t ask me how much). According the article I read about link building it should boost the traffic to your site because people are reading your lens and there would be also a good Google PageRank after a while.

Outdated links on 3rd party websites or search engines are bad for the webmaster and visitor. Most of the time these error’s are handled by some default error page or by some custom code provided via the hosting control panel. Today we discussed at Webdigity the use of a custom error page script with some additional features:

• Report error’s with important server/client information by e-mail to the webmaster
• check 404 errors against a list of known URL’s with bad links
• check for IP addresses from websites with outdated direct links (for example images)

This way it’s possible to know about dead links and the visitor is getting some goog looking and clear error page while he is following an outdated link.

The whole script can be downloaded from the tutorial section at Webdigity
