28042 Simple php code-take 5 minutes

I need a php code to display keywords from the url that the visitor is on. Example: If I was on [login to view URL] the code would allow me to echo "golf swing" wherever I wanted on the page. This means that the code would need to remove all dashes and just display the keywords. I would also want the code to remove any numbers as well. Example: If I was on [login to view URL] the code would allow me to echo "golf swing" wherever I wanted on the page. In addition, I would also like a separate snippet of code that will display the title case of the keywords. Example: If I was on [login to view URL] the title case version of the code would allow me to echo "Golf Swing" wherever I wanted on the page. After you supply me with the code I should be able to easily figure out how to use the code with regular urls (non-blogspot), like with [login to view URL] the code would display/echo "dog party". This should take a good php coder a couple minutes to create. Thanks!
