php parse json data from google directions

I'm trying to parse json data from google directions but can't seem to access 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 is (some) of the json data returns: 

{ "routes" : [ { "bounds" : { "northeast" : { "lat" : 41.90085000000001, "lng" : -87.62979000000001 }, "southwest" : { "lat" : 34.052360, "lng" : -118.243560 } }, "copyrights" : "Map data ©2012 Google", "legs" : [ { "distance" : { "text" : "2,015 mi", "value" : 3243390 }, "duration" : { "text" : "1 day 8 hours", "value" : 114318 }, "end_address" : "Los Angeles, CA, USA", "end_location" : { "lat" : 34.052360, "lng" : -118.243560 }, "start_address" : "Chicago, IL, USA", "start_location" : { "lat" : 41.87811000000001, "lng" : -87.62979000000001 }, "steps" : [ { "distance" : { "text" : "0.2 mi", "value" : 269 }, "duration" : { "text" : "1 min", "value" : 34 }, "end_location" : { "lat" : 41.87570, "lng" : -87.62969000000001 }, "html_instructions" : "Head \u003cb\u003esouth\u003c/b\u003e on \u003cb\u003eS Federal St\u003c/b\u003e toward \u003cb\u003eW Van Buren St\u003c/b\u003e", "polyline" : { "points" : "eir~FdezuOhFIF?HAdFG" }, "start_location" : { "lat" : 41.87811000000001, "lng" : -87.62979000000001 }, "travel_mode" : "DRIVING" }, { "distance" : { "text" : "0.2 mi", "value" : 328 }, "duration" : { "text" : "1 min", "value" : 51 }, "end_location" : { "lat" : 41.875680, "lng" : -87.63366000000002 }, "html_instructions" : "Turn \u003cb\u003eright\u003c/b\u003e onto \u003cb\u003eW Congress Pkwy\u003c/b\u003e", "polyline" : { "points" : "czq~FpdzuO?jE@nEBfGAtB" }, "start_location" : { "lat" : 41.87570, "lng" : -87.62969000000001 }, "travel_mode" : "DRIVING" }, { "distance" : { "text" : "14.0 mi", "value" : 22564 }, "duration" : { "text" : "17 mins", "value" : 1031 }, "end_location" : { "lat" : 41.873870, "lng" : -87.903170 }, "html_instructions" : "Continue onto \u003cb\u003eI-290 W\u003c/b\u003e", "polyline" : { "points" : "_zq~Fj}zuOCtD?fA?f@?pC?P?T@V@zJ?@@T?J?J?F?N?@?J?J?N?p@@xA?h@?B?~A@xD?h@?lB?n@@n@?n@?B@~G?f@A\\EvAGnBEz@EpA?JBlC?F?F?T?B?f@HtM?R?J?t@?|CCvDAb@E`EGlDKzCCd@OrBa@rFGfAAd@?HAp@?`ADbJDzJ?fB?dENdFB~N?d@?RFlH@~C?J@~A?H?XFrKAx@@l@?n@@^@bANnQ?rAAnMCnC@tH@x@FxJ?hB@tM?j@?p@BxFLrT?B?H?jQBbG@|AHxLBVJ~CLfC\\|EHtAHtAVpDf@tF\\dFTxCXhDVzBNtCFlEB|HBvEDlRAhC?xANxU@^?~A?nADxW@vA?l@Dv[?|@?\\@bCHdI@z@ZxDh@zDRx@T|@t@dCPf@bBlEf@dB^vA^jCR`CDv@?LHfBH`X?z@F|V@pF?`@L|Y@v@@dKDbO?jEDdHZjHR`EBd@D`@h@~IHpB@p@@n@?p@BjACvFE`IMrIQzIKfEc@tQEjCCn@}@dUSjFCf@mA~[Ar@QlMObGWlEEx@sB`_@Ep@aBt\\EdA?FcAbU?XCrCKnC?zBR|LB`@B\\?Dz@hG@F@Ft@vDJl@pBfMnAtHZ|ERrEJhTH|GLvJ^rHr@|HX`G@`FLnX@`B?`A@|CAbCRnT?BJ`OHrJDbC@r@XzZ?@DfHMdIe@bHIhD@zHPhP?@@V@fBN|O?T@j@DnEHpQFlGDtCDtEDrEFlEt@jJF~@`@dDPtAXtCd@`IFlC@j@?j@?hAHpLB~C@bDA|DErBCl@Av@O`C]~DWzB[lB[fB]zAo@dCc@~Am@jBo@bBoCxG?@Sd@g@vAY~@St@W|@_@bBUhAYdB]vBMhA[vCKtAEbAIxA?PAXCb@AhA" }, "start_location" : { "lat" : 41.875680, "lng" : -87.63366000000002 }, "travel_mode" : "DRIVING" }, { "distance" : { "text" : "140 mi", "value" : 224957 }, "duration" : { "text" : "2 hours 13 mins", "value" : 8008 }, "end_location" : { "lat" : 41.53651000000001, "lng" : -90.32902000000001 }

You can easily get all the data in json or array format:

$url = "https://maps.googleapis.com/maps/api/directions/json?origin=28.704059,77.102490&destination=30.719059,76.748704&sensor=false";

$jsonfile = file_get_contents($url);

$jsondata = json_decode($jsonfile);

echo $jsondata->routes[0]->legs[0]->distance;

if this error occur:

Catchable fatal error: Object of class stdClass could not be converted to string

than plz use for a output print_r() function

Google already returns JSON, so you do not need to encode it first. Secondly the 'distance' key is deeper in the response structure:

 $origin      = "Rome, Italy";
 $destination = "Venice, Italy";
 $key = "YOUR-OWN-KEY";
 $url = "https://maps.googleapis.com/maps/api/directions/json?origin=".urlencode($origin).",IL&destination=" . urlencode( $destination) . "&sensor=false&key=" . $key;
 $jsonfile = file_get_contents($url);
 $jsondata = json_decode($jsonfile);
 echo $jsondata->routes[0]->legs[0]->distance;
