title: How can I search the text of a list of webpages and return which pages contain that text?
body: <p>What I am aiming to do is search several HTML webpages for a specific string. Then, take the pages that contain that string and echo them back.</p>
  
  <p>Say, take all the webpages on "example.com/php" and search for "foobar".
  What should happen is there should be a list echoed that lists the URLs that contained "foobar".</p>
  
  <p>I'm using a simple HTML form and using POST to a PHP page, but I have not found a method to go through the webpages quickly and return a list.</p>
  
  <p>Thanks for the help.</p>
