title: PHP script to log the raw data of POST
body: <p>I am sending data using HTTP <a href="https://en.wikipedia.org/wiki/POST_%28HTTP%29" rel="nofollow noreferrer">POST</a> to my server. But in the server, I am not receiving the data. And somehow I don't have any way to check the data (or debug script) on client side. But on the client side I am getting HTTP 200, meaning data is sent. Also I can see the connection and data sending was successful. However, log in the server doesn't contain the data (only the number of bytes).</p>
  <p>How can I log the raw POST data that was sent to the server?</p>
  <p>FYI, here the client is an embedded device with very limited capability, so this is a problem. I can not check &quot;print_r&quot; or &quot;echo&quot;.</p>
