Może mi ktoś wytłumaczyć dlaczego występują te błędy?

Skrypt znalazłem w sieci, nie zmieniałem nic oprócz IP i portu
używam vertrigo, a plik nazwałem index.php
<?php if (!$server) { $server_ip = "178.20.168.72"; // ik typte gewoon wat in $server_port = "12203"; // ik typte gewoon wat in } else { $server_ip = $server[0]; $server_port = $server[1]; } // Do NOT change anything below this line! // Creating the URL for the connection: $server_ip = "udp://" . $server_ip; // Open the connection: // Set the timeout: // Get the information from the server, and put it into the $output array: $send = "??" . chr (0x02) . "getstatus";
do { } while ($status_pre[unread_bytes] != $status_post[unread_bytes]); }; // Close the connection: // Select the variables from the $output array: $max_clients = $output[$max_index+1]; $mapname = $output[$max_index+1]; $hostname = $output[$max_index+1]; $gametype = $output[$max_index+1]; $players_string = $output[$last_value]; $players_string[0] = $get_first_ping[1]; $i = 1; $players = 0; $i++; $i++; $players++; } // Create the image url: } else { } $picture_src = "images/" . $picture_src .
