I am trying to parse json data from google directions, but cannot access any of the values. Here is the PHP code:
$url = "http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles&sensor=false"; $jsonfile = json_encode(file_get_contents($url)); $jsondata = json_decode($jsonfile); echo $jsondata->distance;
here (some) of the json data is returned:
