Cloaked content generator

This is a cloak / dynamic content generation script. It is the first one made by myself. The first thing considered was if I should base the cloaking on IP addresses or user-agent. Many people say IP addresses is the best way since search engines spoof their user-agents to try catch people out… thing is, im sure they also use unofficial IP ranges to catch people so I have stuck with the user-agent method since this requires the least maintenance for the end user(YOU!) To use it you simply add a small peice of code to the top of each page you wish to be cloaked. When someone accesses your page then cloakgen is ran and if the user-agent suggests the visitor is a standard user then they are simply shown your standard page. However if the user-agent suggests that the visitor is a search engine then it will start doing the business. It will start by finding out what page called it, then it will open this page and find out what the most common words on the page are. Once it has worked this out then it will scrape some content about that word from wikipedia and add it with your normal page content. Each keyword will be emphazied in a random way. For example the keyword could be bold or red font etc. The final page will be output in the following way:

Title of the page in capital letters
Large title at the top of the page
Content of the website with emphasization and wiki content
