$city = $user->address->city;Description:
To extract data from a JSON string in PHP first convert it to a JSON object using the json_decode method. The json_decode() method takes a JSON encoded string and converts it into a PHP variable.
$data = json_decode($jsonString);
null is returned if the JSON cannot be decoded or if the encoded data is deeper than the nesting limit.
By default, the json_decode method returns an stdClass object. You can get the result as an associative array if sets the second parameter to true:
$dataArray = json_decode($jsonString, true);
So accessing data in JSON object is as simple as:
$city = $user->address->city;
