Socket_connect producing errors that show no reason

The code looks like this: if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0){

    print("Couldn't Create Socket: " . socket_strerror(socket_last_error()). "\n");

} socket_set_option($sock, SOL_SOCKET,SO_RCVTIMEO, array('sec' => 1, 'usec' => 0)); $output = ''; for($i = 0; $i < count($file); $i++){

    $servernum = $file[$i];
    $i++;
    $servername = $file[$i];
    $serverport = $file2[$i];
    $serverport = preg_replace('/\s/','',$serverport);

    // Test if server online - if not, output offline. If yes, output Online.
    if(!socket_connect($sock, $ip, $mapport)){
        print("Couldn't Create Socket: " . socket_strerror(socket_last_error()). "\n"); // Debug
        $output .= "Server Name: " . $servername. " ~~ Offline <br />";
        continue;
    }
    else{
        $output .= "Server Name: " . $servername. " ~~ Online <br />";
    }

} My problem now is that as it runs through the loop - it has a connection error. Warning: socket_connect() [function.socket-connect]: unable to connect [106]: Transport endpoint is already connected in status.php on line 17 Even looking at examples, I cannot figure out why this error is being produced. I cannot close the socket at the end of the loop, as it would make any further attempts for online status impossible. The socket_close($sock) is directly after the loop. Thanks for any help!
