10. Link-Verification Webbots > Further Exploration

Further Exploration

You can expand this basic webbot to do a variety of very useful things. Here is a short list of ideas to get you started on advanced designs.

  • Create a web page with a form that allows people to enter and test the links of any web page.

  • Schedule a link-verification bot to run periodically to ensure that links on web pages remain current. (For information on scheduling webbots, read Chapter 22.)

  • Modify the webbot to send email notifications when it finds dead links. (More information on webbots that send email is available in Chapter 15.)

  • Encase the webbot in a spider to check the links on an entire website.

  • Convert this webbot into a function that is called directly from PHP. (This idea is explored in Chapter 16.)
