json and php question
<p>I am using the following in php to return the driving distance details between 2 locations:</p>

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

<p>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.</p>

<p>Thanks in advance.</p>
