How to get JSON response?

Question

PHP

This code should receive JSON and then decode it, and output it online to site.ru/?online. So why doesn't it work?

$server = @file_get_contents('http://api.minetools.eu/ping/lobby.freecraft.eu/25565');
$tree = json_decode($server);
if(isset($_REQUEST['online'])){ 
exit("{$tree['players']['online']}");
}

Answer 1

1. Check that the data is written to $server
2. json_decode([json], true) - the true flag sets json parsing into an array, now you have an object after json_decode $tree.
