laravel 4获取给定密钥的JSON值

Question

I'm using:

$location = file_get_contents($mapurl);

which responds with json:

{
  "results" : [],
  "status" : "ZERO_RESULTS"
}

how can I extract a value for a given key ?

I've tried:

$status = $location::get('status');

but this is throwing errors.

Answer 1

Try

$location = json_decode(file_get_contents($mapurl));
$status = $location->status;

file_get_contents returns a string, you have to call json_decode convert it to an object then you can access the status property.
