read the keywords from a site

Hello
I like to read the url and the keywords from an url an write them in an MySQL Database. But i didn't now how i should start this.
Is anybody there who can help me a little

Thanks

Any values passed to a page (thru GET or POST) are automatically available as variables in PHP.

So if the following is my URL:

http://www.foo.com/index.php3?foo=one

Then in my script, $foo will automatically have the value of "one".

From there, your script can collect the info and insert it into MySQL using the usual MySQL functions.
