title: reverse serialize() -jquery
body: <p>I sent my data (json) for an ajax request with this code;</p>
  
  <pre><code>var formdata = $("#customForm").serialize();
  
              type: "post",
              dataType: "json",
              data: formdata,
  </code></pre>
  
  <p>In the php file, there is possible reverse the serialize? </p>
  
  <p>or i need to make  something like that: <code>$pass = $_POST['pass'];</code> for all fields?</p>
  
  <p>thanks</p>
