Why am I not getting a JSON response in the config when I send a GET request using PHP?

Question

PHP

The task scheduler sends a request to get ip:port and receives the online_p and max data from JSON and then writes it to the config ...

Cron gives such an error and does not write anything, can someone tell me what's wrong and where did I make a mistake? I've been suffering for half a day, sorry for my broken php language...

Tobish in order: Cron performs the task then checks which server to choose where the true function is enabled, then it selects the same data from the API using json and writes it to the config for the number of online players, but the cron does not do this, that is, an error pops up

Answer 1

Use the library from xPaw

Answer 2

You would at least check for the existence of data, would ...

foreach ($config['servers'] as &$server) {
        if (!isset($response[$server['host']. ':' .$server['port']])) continue;
        $rData = $response[$server['host']. ':' .$server['port']];
        if (isset($rData['status']) AND $rData['status'] === true) {
            $server['onlinePlayers'] = $rData['players']['online'];
            $server['totalPlayers']  = $rData['players']['max'];
        } else {
            $server['onlinePlayers'] = 0;
            $server['totalPlayers']  = 0;
        }
    }

Answer 3

If you open your eyes and read the error, then the old cron works for you, not the new one.
