In PHP, the sockets extension can be used to create and manage network socket connections. Here are common use cases for using the sockets extension:

  1. create a socket
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
  1. bind the socket
socket_bind($socket, '127.0.0.1', 8000);
  1. Start listening on a socket
socket_listen($socket);
  1. Accept a socket connection
$newSocket = socket_accept($socket);
  1. write to a socket
  2. read from a socket
$message = 'Hello, World!';
socket_write($newSocket, $message, strlen($message));

$data = socket_read($newSocket, 1024);
  1. close the socket
socket_close($socket);

These are common use cases in the sockets extension, which can be adjusted and used accordingly based on specific requirements and socket types.
