Use PHP to develop the C/S structure _ PHP Tutorial-php Tutorial

Use PHP to develop the CS structure. Server? PhpServer sets error handling error_reporting (E_ALL); sets the runtime set_time_limit (0); uses the buffer ob_implicit_flush (); $ ip127.0.0.1; IP address server

// Server

// Set error handling

Error_reporting (E_ALL );

// Set the running time

Set_time_limit (0 );

// Starting buffer

Ob_implicit_flush ();

$ Ip = "127.0.0.1"; // ip address

$ Port = 1000; // port number

$ Socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP); // Create a SOCKET

If ($ socket)

Why? Php // Server // Set error handling error_reporting (E_ALL); // Set the runtime set_time_limit (0); // The buffer ob_implicit_flush (); $ ip = "127.0.0.1 "; // IP address...
