The port is already listening, why Fsockopen will fail, how to handle it

Port is already in listening state, why Fsockopen will fail
View with netstat-a command, display TCP 0.0.0.0:2012 www:0 LISTENING
But with the PHP socket access, the code is as follows:

PHP Code

  
  $fp = Fsockopen (' 202.117.xxx.xxx ', $errno, $errstr, ten); Echo $fp;

Why do I also prompt unable to connect to 202.117.xxx.xxx:2012 (cannot connect because the target computer is actively rejecting it.) ?)?

------Solution--------------------
Isn't that the other person's refusal?

Ping 202.117.xxx.xxx:2012
Or
Telnet 202.117.xxx.xxx:2012

Look
------Solution--------------------
LocalHost to even try?
------Solution--------------------

PHP Code

$socket = Socket_create (Af_inet, Sock_stream, sol_tcp);   $connection = Socket_connect ($socket, ' 192.168.xxx.xxx ', 2012);
