title: How to improve PHP string match with similar_text()?
body: <p>I am using PHP's similar_text() call to compare two strings, however, I am not getting good enough results, for example, the best I'm getting is 80.95% for a match that I'd like to see 100% on.</p>
  
  <p>What other functions can I use to get the strings down to the core?</p>
  
  <pre><code>&lt;!-- Overcast, Rain or Showers compared Overcast, Rain or Showers is 80.9523809524 --&gt;
  &lt;!-- Overcast, Risk of Rain or Showers compared Overcast, Rain or Showers is 86.2068965517 --&gt;
  &lt;!-- Overcast, Chance of Rain or Showers compared Overcast, Rain or Showers is 83.3333333333 --&gt;
  </code></pre>
