title: How to send a value from PHP to NodeJS, then back to PHP?
body: <p>All I want to do is to send a value from PHP to NodeJS for processing.
  Then when NodeJS finished processing the value, send the value back to PHP.</p>
  
  <p><strong>Desired PHP:</strong></p>
  
  <pre><code>&lt;?php
     $value = 'someVal';
     $url = 'http://123.456.789:8080/processing/'
  
     $newValue = mysteriousFunctionThatSendsTheDataToNodeJSThatIDontKnowAbout($url, $value);
  ?&gt;
  </code></pre>
  
  <p><strong>Desired NodeJS:</strong> </p>
  
  <pre><code>router.post('/processing/', function(request, response){ 
     var value = request.body.value;
  
     //VALUE BEING PROCESSED
  
     response.send(value);
  });
  </code></pre>
  
  <p>Some notes: Doesn't matter if it it is router.post or router.get or router.whatever, I just need the value go from PHP to NodeJS then back to PHP.</p>
