Print Search Engine Queries via PHP.

This will be easy for someone who knows PHP. My intent is to build a database of search queries for each page of my website. I need to be able to pull the search strings a website visitor used on a search engine that brought visitors to my site. project scope: Write a PHP code segment that I will include (include "[login to view URL]";) in each of my web pages. From there I want to be able to print the search phrase that the user entered into the search engine. example: print "$query"; Also, since I will be building a database of search engine queries for each of my landing pages, I need to know the landing page of the query. Example: print "$landing_page"; would show the page that the user landed on when sent by the search engine. I would also like to know the search engine that sent the user to my site so I can also print it. example: print "$search_engine<br>"; will print Google, Bing or Yahoo. I am only interested in tracking the following search engines: [login to view URL] [login to view URL] [login to view URL] All other search engines can be ignored. You will not need to worry about the database. I will take care of that. A successful project will allow me to enter the following code in each of my pages: <?php include "[login to view URL]"; print "$query<br>"; print "$search_engine<br>"; print "$landing_page<br>"; ?> The results then would look like: ask uncle ralph [login to view URL] [login to view URL]
