Answer 1

There's a simple text protocol. You
open a socket, a bit of conversation, and now you know if they want to communicate with you. Then close the socket.

Answer 2

leave a snippet

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$res = socket_connect($socket, $address, $port);
    if($res){
        echo 'Redis connected';
        socket_write ( $socket , 'auth password'.PHP_EOL );
        echo socket_read($socket, 100); //если все ОК, получаем ответ: +OK\r\n
    }
socket_close ( $socket );
