What is wrong wd these codes?

With regards

@phpuser123,

Please use code tags around your programs in the future. It's simple, just place a line the words "code" and "/code" in square brackets above and below your code.

Your problem is that your server refused the IP connection, right?

That means that your server isn't running, it's running on a different port, or there's a firewall in the way, or maybe you got the server's IP address wrong.

Luck!
