title: jQuery UI autocomplete wont display returned json (PHP)
body: <p>The jQuery:</p>
  
  <pre><code>$("[type=text]").autocomplete({
  source: "json.php",
  minLength: 0
  }).addClass("ui-widget ui-widget-content ui-corner-left");
  </code></pre>
  
  <p>Works fine if I change the source: to a JS array.  I know that the php is working because I can see it in the console, but here is the sample php anyways:</p>
  
  <pre><code>$arr = array ('a'=&gt;1,'b'=&gt;2,'c'=&gt;3,'d'=&gt;4,'e'=&gt;5);
  echo json_encode($arr);
  </code></pre>
  
  <p>So the dropdown just isn't displaying.  Feeling pretty stupid right about now.</p>
