title: Read Angular2 POST data in PHP
body: <p>I want to connect my angular2 app to my PHP backend. Ideally I want to do this:</p>
  
  <pre><code>this.http.post('/users/create', {email: email, password: password});
  </code></pre>
  
  <p>The problem is, when I do this my <code>$_POST</code> is empty in PHP. What must I do to make this work?</p>
