title: Max POST data limit
body: <p>I have this problem: Not all POST data are sent from the browser or not are available on the form's action page.</p>
  
  <p>I need to know:</p>
  
  <ul>
  <li>what are the causes?</li>
  <li>how to control what is the cause?</li>
  <li>how to fix this?</li>
  </ul>
  
  <p>The action's page doesn't return any error (even if I <code>set error_reporting(E_ALL);</code> ). The server is Linux. The form's input are many, some are arrays with a maximum level of two nested keys (<code>array[1][2]</code>).</p>
  
  <p>I tried to send less inputs and it works, but I need to use all the inputs in the page.</p>
  
  <p>I printed all the POST data received by the form's action page and the last inputs there aren't in the <code>$_POST</code> variable.</p>
  
  <p>Thanks</p>
