PHP是一门高效的网络编程语言，由于它具有编写灵活、运行快速等优点，迅速成为Web程序员的`首选语言。以下是小编为大家搜索整理的PHP开发CS结构的技巧，希望能给大家带来帮助!更多经常内容请及时关注我们应届毕业生考试网!
核心提示：用PHP开发C/S结构。
服务器
// Server
// 设置错误处理
error_reporting E_ALL;
// 设置运行时间
set_time_limit 0;
// 起用缓冲
ob_implicit_flush ;
$ip = "127.0.0.1"; // IP地址
$port = 1000; // 端口号
$socket = socket_create AF_INET, SOCK_STREAM, SOL_TCP; // 创建一个SOCKET
if $socket
echo "socket_create successed!\n";
else
echo "socket_create failed:".socket_strerror $socket."\n";
$bind = socket_bind $socket, $ip, $port; // 绑定一个SOCKET
if $bind
echo "socket_bind successed!\n";
else
echo "socket_bind failed:".socket_strerror $bind."\n";
$listen = socket_listen $socket; // 间听SOCKET
if $listen
echo "socket_listen successed!\n";
else
echo "socket_listen failed:".socket_strerror $listen."\n";
while true
$msg = socket_accept $socket; // 接受一个SOCKET
if !$msg
echo "socket_accept failed:".socket_strerror $msg."\n";
break;
$welcome = "Welcome to PHP Server!\n";
socket_write $msg, $welcome, strlen $welcome;
while true
$command = strtoupper trim socket_read $msg, 1024;
if !$command
break;
switch $command
case "HELLO":
$writer = "Hello Everybody!";
break;
case "QUIT":
$writer = "Bye-Bye";
break;
case "HELP":
$writer = "HELLO\tQUIT\tHELP";
break;
default:
$writer = "Error Command!";
socket_write $msg, $writer, strlen $writer;
if $command == "QUIT"
break;
socket_close $msg;
socket_close $socket; // 关闭SOCKET
?>
客户端
// Client
// 设置错误处理
error_reporting E_ALL;
// 设置处理时间
set_time_limit 0;
$ip = "127.0.0.1"; // IP 地址
$port = 1000; // 端口号
$socket = socket_create AF_INET, SOCK_STREAM, SOL_TCP; // 创建一个SOCKET
if $socket
echo "socket_create successed!\n";
else
echo "socket_create failed:".socket_strerror $socket."\n";
$conn = socket_connect $socket, $ip, $port; // 建立SOCKET的连接
if $conn
echo "Success to connection![".$ip.":".$port."]\n";
else
echo "socket_connect failed:".socket_strerror $conn."\n";
echo socket_read $socket, 1024;
$stdin = fopen ´php://stdin´, ´r´;
while true
$command = trim fgets $stdin, 1024;
socket_write $socket, $command, strlen $command;
$msg = trim socket_read $socket, 1024;
echo $msg."\n";
if $msg == "Bye-Bye"
break;
fclose $stdin;
socket_close $socket;
?>
