Example of PHP + SOCKET

PHP + SOCKET example Client sets error handling error_reporting (E_ALL); set_time_limit (0); $ ip; ip address $ port1000; port number $ socketsocket_create (a php + SOCKET example)

// Client // sets error handling error_reporting (E_ALL); // sets the processing time set_time_limit (0); $ ip = ""; // IP address $ port = 1000; // port number $ socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP); // A SOCKETif ($ socket) echo "socket_create () is created successfully!

\ N "; else echo" socket_connect () failed: ". socket_strerror ($ conn )."
\ N "; echo fig ($ socket, 1024 )."
"; $ Stdin = fopen ('php: // stdin ', 'r'); $ ar = array (" HELLO "," HELP "," test ", "QUIT"); $ I = 0; while (true) {// $ command = trim (fgets ($ stdin, 1024); // socket_write ($ socket, $ command, strlen ($ command); echo "send $ ar [$ I]
