While you now have a search application that you can use on your web site, it was not our intention to only provide a script that you can use. We hope that by learning to develop this search application you have a greater understanding of how PHP works. It is also our desire that the foundations learned for databases in this tutorial will pave the way for you to learn more about them.
There are many ways you could extend this search application. For instance, we mentioned earlier that you could develop a spider to harvest the keywords. While this is not a simple undertaking, it would be an excellent learning tool. You could also extend this application to harvest keywords from data already stored in a database and display the relevant content when a match was made. Use your imagination and then start coding. With a little determination and a lot of study, you will be amazed at the applications you can create with PHP.
