title: jQuery $.post and json_encode is returning a string with quotes around it
body: <p>I'm using jQuery's $.post call and it's returning a string with quotes around it. The quotes are being added by the json_encode line. How do I stop this from adding quotes? Am I missing something in my $.post call?</p>
  
  <pre><code>$.post("getSale.php", function(data) {
      console.log('data = '+data); // is showing the data with double quotes
  }, 'json');
  </code></pre>
