json and php question

Question

I am using the following in php to return the driving distance details between 2 locations:

$url = 'http://maps.google.com/maps/nav?q=from:London%20to:Dover';
$data = @file_get_contents($url);

A JSON object is returned, i am not familiar with JSON can somebody please demonstrate how I can get the "Meters" element from this object into a string.

Thanks in advance.

Use json_decode:

$obj = json_decode($data);
echo $obj->Directions->Distance->meters;

@brux You should know that the property name is "meters" with a lowercase "m".

You might want to look at the json_decode() function...

$url = 'http://maps.google.com/maps/nav?q=from:London%20to:Dover';
$data = json_decode(@file_get_contents($url));

echo $data->Directions->Distance->meters." meters";

Result:

123561 meters

Use json_decode. JSON Decode

$url = 'http://maps.google.com/maps/nav?q=from:London%20to:Dover';
$data = @file_get_contents($url);
$obj = json_decode($data);

Try this online json Viewer you can call JSON.parse in javascript to parse the string php output to a javascript object.

var json = {}; // parsed json object

var meters = json.Directions.Distance.meters; // is '123561'
