title: PHP does not display error messages
body: <p>I installed XAMPP 1.7.4 (with PHP 5.3.5), the problem is PHP does not display any error messages. E.g. if I connect to MYSQL with <code>mysql_connect()</code> without parameters, PHP will not complain about the required fields.</p>
  
  <p>Why is this?</p>
  
  <p>How can I configure PHP to display errors?</p>
