初学求教，

岁月如歌

请大侠指教，下面代码怎么老提示下面的错误？
Connection failed.n无法立即完成一个非阻挡性套接字操作。 (10035)

<?php

$cfgServer = "211.X.28.67";
$cfgPort = 21;
$cfgTimeOut = 5;

//open a socket
if(!$cfgTimeOut)
     // without timeout
     $usenet_handle = fsockopen($cfgServer, $cfgPort);
else {
     // with timeout
     $usenet_handle = fsockopen($cfgServer, $cfgPort, &$errno, &$errstr,

$cfgTimeOut);
     set_socket_blocking( $usenet_handle, true );

}
echo "1\n";
if(!$usenet_handle) {
echo "Connection failed.n";
echo "$errstr ($errno)\n";
exit();
}
else {
echo "Connected.n";
$tmp = fgets($usenet_handle, 1024);
echo "$tmp";
}
echo "2\n";

exit();
?>;
