在PHP服务器套接字编程中无法绑定相同的端口

Question

I am trying to bind socket with same port, I am getting error.

socket_bind(): unable to bind address [0]: Only one usage of each socket address (protocol/network address/port) is normally permitted. in C:\xampp\htdocs\my\server.php on line 79 Could not bind to socket

Here is 79-th line:

$result = socket_bind($socket, $host, $port) or die("Could not bind to socket
");

How to fix this?

Use a different port or kill the application that is bound to the port you are trying to bind to. Generally speaking only 1 application can be bound to a port at a time.

netstat -O is used to find ports that are in use via cmd in windows.
