title: Convert a percentage into a decimal and remove percent sign in PHP?
body: <p>What is the best way to move a decimal over two places and remove the percentage sign in PHP?</p>
  
  <p>For example:</p>
  
  <p><code>9.5%</code> turns into <code>.095</code></p>
  
  <p>Is there a special function for this?</p>
