title: PHP/MYSQL match a sentence against keywords?
body: <p>I have a text that can be a 255 chars long.
  And I have a db containing keywords.
  Is there a way in PHP or MYSQL to test the sentence in order to find matching keywords? (kind of like StackOverflow does suggesting tags after typing the question)</p>
  
  <p>eg.the text is:</p>
  
  <blockquote>
    <p>The New York Times: Find breaking news, multimedia, reviews &amp; opinion
    on Washington, business, sports, movies, travel, books, jobs.</p>
  </blockquote>
  
  <p>and say my mysql DB contains <code>newspaper, news, book.</code></p>
  
  <p>I'm not sure where to start... what is the best approach?</p>
