title: PHP Curl, where can I find a list of integer equivelants of constants
body: <p>I'm using the Codeigniter Curl library, and the author uses the integer equivalents of the curl options. The php manual says this for <a href="http://us2.php.net/manual/en/function.curl-setopt-array.php" rel="noreferrer">curl_setopt_array</a>:</p>
  
  <blockquote>
    <p>The keys should be valid curl_setopt()
    constants or their integer
    equivalents.</p>
  </blockquote>
  
  <p>How do I figure out what the integer equivalents are for a constant? I've googled it but haven't found anything.</p>
  
  <p>Thanks, Mark</p>
