title: PHP - ZipArchive is enabled but not found
body: <p>When I look at <code>phpinfo</code> I see that Zip is enabled:
  <img src="https://i.stack.imgur.com/7uZ31.png" alt="enter image description here"></p>
  
  <pre><code>extension_loaded('zip') // &lt;- returns true.
  function_exists('zip_open') // &lt;- returns true.
  class_exists('ZipArchive', false) // &lt;-returns false.
  </code></pre>
  
  <p>When I try to create a ZipArchive object, I get error: <code>Fatal error:  Class 'ZipArchive' not found</code></p>
  
  <p>PHP Version 5.4.11</p>
