// Create a socket resource $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); // Connect to the server $address = 'localhost'; $port = 9000; $result = socket_connect($socket, $address, $port); // Send the configuration file to the server $configFile = 'config.ini'; $fileData = file_get_contents($configFile); $bytesWritten = socket_write($socket, $fileData, strlen($fileData)); // Close the socket socket_close($socket);In this example, we first create a socket resource using the `socket_create()` function. We then connect to the server using the `socket_connect()` function, specifying the server's address and port number. Next, we read in the contents of the configuration file using `file_get_contents()`, and then use the `socket_write()` function to send the file data to the server over the socket connection. Finally, we close the socket using `socket_close()`. Note that there are many different PHP socket functions available, and the specific one(s) you use will depend on your specific use case. As for the package library, again, I cannot determine it without more information.
