title: PHP - How to get tokens?
body: <p>I was told I needed to validate the tokens below but I'm not sure where to start. I only have public access to the website I'm pulling the data from. Someone explain to me tokens or give an example to get me moving?</p>
  
  <p>Do I need access to the other server?</p>
  
  <pre><code>function send_CAD($number, $street, $website, $f_opts = true){         
      $year   = date('Y', time());    
      $number = trim($number);
      $street = urlencode(trim($street));
      $post_data = "__EVENTTARGET=&amp;__EVENTARGUMENT=&amp;".
                   "__VIEWSTATE=/wEPD...&amp;" .
                   "__EVENTVALIDATION=/wEWNw...&amp;".
                   "txtAddrNum=$number&amp;listStDir=&amp;";
  ...
  </code></pre>
