JSON

In my php code, I am retrieving json data as below.

<?php
$url = "http://dbpedia.org/data/Los_Angeles.json";
$data = file_get_contents($url);
echo $data;
?>

The javascript code consumes this json data returned from php and gets the json object as below.

var doc = eval('(' + request.responseText + ')');

How to retrieve the following json data using dot notations. The keys contain URLs.

"http://dbpedia.org/ontology/populationTotal" : [
{ "type" : "literal",
  "value" : 3792621 ,
  "datatype" : "http://www.w3.org/2001/XMLSchema#integer" } ] ,
"http://dbpedia.org/ontology/PopulatedPlace/areaTotal" : [
{ "type" : "literal",
  "value" : "1301.9688931491348" ,
  "datatype" : "http://dbpedia.org/datatype/squareKilometre" }
