Question

How do I access user_id:
This is the print_r of my cookie:

Array
(
     [PHPSESSID] => gv0hsh6uel9kiuprdoc0uqboq4
     [oauth_token] => 40533855-FNM77JeuJIPdKclYyaT2Fi9jZRu2NGAHh5FeveNk
     [oauth_token_secret] => C6GDTEu60rGa4aDbqjncm6yfUf9Xc9520AuX9GXag
     [SocialAuth] => a:2:{s:4:"type";s:8:"facebook";s:7:"user_id";s:2:"22";}
     [__utma] => 157144508.1187834205.1333154906.1333154906.1333154906.1
     [__utmb] => 157144508.35.10.1333154906
     [__utmc] => 157144508
     [__utmz] => 157144508.1333154906.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)
)

My user ID in this is at the end of the SocialAuth line… “22”. But I cant seem to access it.

$user = $_COOKIE["SocialAuth"]["user_id"];

Returns “a”.

Am I doing this right?
Thanks in advance.

Answer 1

You have a serialized array in $_COOKIE['SocialAuth']. Take a look at the manual pages for serialize and unserialize.

Use unserialize like this to access the user id:

$user = unserialize($_COOKIE['SocialAuth'])['user_id'];

Or prior to PHP 5.4:

$arr = unserialize($_COOKIE['SocialAuth']);
$user = $arr['user_id'];
