title: How to get body of a POST in php?
body: <p>I submit as POST to a php page the following: </p>
  
  <pre><code>{a:1}
  </code></pre>
  
  <p>This is the body of the request (a POST request).<br>
  In php, what do I have to do to extract that value?  </p>
  
  <pre><code>var_dump($_POST); 
  </code></pre>
