Json Decode From URL Not Working

Question

I'm trying to use the mojang api to retrieve a users Minecraft UUID from their Username this is what i have:

//Get Player UUID from name
$uuid = "Error obtaining uuid";
$json = file_get_contents('https://api.mojang.com/users/profiles/minecraft/' + $_GET['name']);
$obj = json_decode($json);
$uuid = $obj->id;

The variable $uuid contains null and im not sure what im doing wrong i made sure i set the $_GET parameters by going to player.php/?name=_Joosh but still nothing?

Is there anything on `$json`? Please, `var_dump($json)`, [edit](http://stackoverflow.com/posts/34486105/edit) your question and post the updates... — FirstOne, Dec 27 '15 at 23:50
Please, check if [allow_url_fopen](http://stackoverflow.com/questions/13433660/how-to-check-if-allow-url-fopen-is-enabled-or-not) is enabled. Also, PHP uses `.` to [concat string](http://php.net/manual/en/language.operators.string.php). — FirstOne, Dec 27 '15 at 23:58
Thank you @FirstOne i was mixing java with php and using + that was my issue, thank you. — Joosh, Dec 28 '15 at 00:12
So, the problem was just with the concat part? I mean, is this solved? — FirstOne, Dec 28 '15 at 00:13

You have to use dot opearator for concatenation not plus. Try the below snippet.

//Get Player UUID from name
$name = 'john';
$uuid = "Error obtaining uuid";
// Tested with simple variable
// $json = file_get_contents('https://api.mojang.com/users/profiles/minecraft/' . $name);
$json = file_get_contents('https://api.mojang.com/users/profiles/minecraft/' . $_GET['name']);
$obj = json_decode($json);
$uuid = $obj->id;

print $uuid;
