Answer 1

Let's suppose the JSON string (or object) is stored in the variable $json.
<?php
// convert your JSON object to a PHP array
$decoded_json = json_decode($json, true);
print_r($decoded_json); // print your PHP array to check how to subindex your new var
// I think it will be something like $decoded_json[0]['hostname']
?>

Answer 2

<?php
$test = '[
[
{
"ip": "176.57.188.22",
"port": "27022",
"rank": "1",
"online": "1",
"hostname": "..:: LS Public Server ::.. #1",
"num_players": "12",
"max_players": "32",
"location": "AL",
"mapa": "de_dust2"
}
],
true
]';
$test = json_decode($test);
echo $test[0][0]->hostname;
//---output---
//..:: LS Public Server ::.. #1
?>

Answer 3

Use json_decode with true as second parameter, it gives you an associative array and it will convert the JSON object into a PHP array.
Try this :
<?php
error_reporting(0);
$test = '[
[
{
"ip": "176.57.188.22",
"port": "27022",
"rank": "1",
"online": "1",
"hostname": "..:: LS Public Server ::.. #1",
"num_players": "12",
"max_players": "32",
"location": "AL",
"mapa": "de_dust2"
}
],
true
]';
$data = json_decode($test,true);
foreach ($data as $info) {
foreach ($info as $result) {
echo $result[hostname];
}
}
?>
