title: Can't retrieve value of JSON Object attr after json_encode in PHP
body: <p>I'm not able to get the value of the <code>image</code> attribute in this (apparently valid) JSON object:</p>
  
  <pre><code>echo var_dump($result);
  
  array(1) {
    ["images"]=&gt;
    array(1) {
      [0]=&gt;
      array(1) {
        ["src"]=&gt;
        string(112) "http://staticf5a.diaadia.info/sites/default/files/styles/landscape_310_155/public/nota_periodistica/taxis_13.jpg"
      }
    }
  }
  
  $jsonResult = json_encode($result); //result is an array of arrays
  echo $jsonResult;
  
  {"images":[{"src":"http:\/\/staticf5a.diaadia.info\/sites\/default\/files\/styles\/landscape_310_155\/public\/nota_periodistica\/taxis_13.jpg"}]}
  
  echo $jsonResult-&gt;images; //show nothing
  </code></pre>
  
  <p>This snippet was working few days ago, and logs (<code>ini_set('display_errors', '0');</code>) don't show anything related.</p>
