title: What is mod_php?
body: <p>While going through a <a href="http://akrabat.com/wp-content/uploads/getting-started-with-the-zend-framework_122.pdf" rel="noreferrer">Zend tutorial</a>, I came across the following statement:</p>
  
  <blockquote>
    <p>Note that the php_flag settings in .htaccess only work if you are using mod_php.</p>
  </blockquote>
  
  <p>Can someone explain what that means?</p>
