title: PHP cast from string to int error
body: <p>Hi when trying to cast from a string to int using <code>int()</code> I get the following error:</p>
  
  <blockquote>
    <p>Call to undefined function int() </p>
  </blockquote>
  
  <p>Why would this be?</p>
  
  <p><code>intval()</code> works just fine but I cannot use <code>int()</code> for some reason.</p>
