title: PHP $_POST does not work
body: <p>I'm working a web application with PHP.
  Something wrong is happening that I have never seen before. <code>$_GET</code> is working well, but <code>$_POST</code> does not work exactly. Imagine the form below:</p>
  
  <pre><code>&lt;form action="process.php" method="post"&gt;
     &lt;input type="text" name="title" /&gt;
     &lt;input type="submit" value="send" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>As you see, I've used post for method attribute of the form. In this case, the code below will return error:</p>
  
  <pre><code>&lt;?php
  $sentData = $_POST['title'];
  echo($sentData);    
  ?&gt;
  </code></pre>
  
  <p>Error message:</p>
  
  <pre><code>PHP Notice:  Undefined index: title in ...
  </code></pre>
  
  <p>But If I had used <code>$_GET</code> in php scripts and <code>get</code> in the html form codes, everything would work without any error.</p>
  
  <p>There are something more strange.</p>
  
  <ol>
  <li>There are just one form that returns no error while I'm using POST, other forms return error. </li>
  <li>When I run this application locally (with Xampp - Apache 2.2) everything works fine without any error, but whenever I run the application an the remote server (IIS 7), I get these errors and problems.</li>
  </ol>
