title: REST client - How to send data with PUT request?
body: <p>I've created a REST API using Codeigniter and I'm testing it with wiztools.org REST client <a href="https://code.google.com/p/rest-client/" rel="nofollow">https://code.google.com/p/rest-client/</a></p>
  
  <p>How can and should I send data for a PUT request? I've seen some PHP examples where JSON is sent in the headers but I'm not sure how to do this in the client I'm testing with or how to read this data from the request. </p>
