从Laravel 4中的Facebook许可位置得出城市和州

Question

I am trying to separate out the city and state from the location array object from Facebook in Laravel. Before when I did this, I simply tried something similar to what I am trying in my Oauth2 Controller:

$citystate = $user['location'];
$citystate2 = $citystate['name'];
$split = explode(", ", $citystate2);
$city = $split[0];
$state = $split[1]; 

In the provider file, Facebook.php, I have this:

'location' => $user->location

However, when I run this, I get the error:

Use of undefined constant name - assumed 'name'

So, my question is, how do I access the "name" portion of the location array object. Thank you for your help!

Answer 1

At first, you should json_decode (if it's a json string) like

$userArray  = json_decode($user, true);

So, you can use it like an array

$citystate = $userArray['location'];

Also you can check if the $user is already an array or not using

if(is_array($user) && array_key_exists('location', $user)) {
    // ...
    $citystate = $user['location'];
    // ...
}

Then you'll get an array like this

array (size=2)
 'id' => string 'xxx' (length=15) // xxx = digits
 'name' => string 'Sylhet' (length=6)

Update : $user['location'] is an object :

object(stdClass)#180 (2) { ["id"]=> string(15) "114952118516947" ["name"]=> string(25) "San Francisco, California" }

So, it should be :

$citystate = $user['location'];
$citystate->name;
