前端之家收集整理的这篇文章主要介绍了
用PHP的socket实现客户端到服务端的通信实例详解,
前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
一、server.PHP服务端:
PHP;">
PHP
error_reporting(E_ALL);
set_time_limit(0);
ob_implicit_flush();
//本地IP
$address = 'localhost';
//设置用111端口进行通信
$port = 111;
//创建SOCKET
if (($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) {
echo "socket创建失败原因 " . socket_strerror($sock) . "\n";
}
if (($ret = socket_bind($sock,$address,$port)) < 0) {
echo "创建套接字失败原因 " . socket_strerror($ret) . "\n";
}
//监听
if (($ret = socket_listen($sock,5)) < 0) {
echo "监听失败原因 " . socket_strerror($ret) . "\n";
}
do {
//接收命令
if (($msgsock = @socket_accept($sock)) < 0) {
echo "命令接收失败原因: " . socket_strerror($msgsock) . "\n";
break;
}
$msg = "\nPHP Test Server. \n" ."用quit,shutdown,sun...等命令测试.\n";
@socket_write($msgsock,$msg,strlen($msg));
do {
if (false === ($buf = @socket_read($msgsock,2048,PHP_NORMAL_READ))) {
echo "socket_read() failed: reason: " . socket_strerror($ret) . "\n";
break 2;
}
if (!$buf = trim($buf)) {
continue;
}
if ($buf == 'quit') {
break;
}
if ($buf == 'shutdown') {
socket_close($msgsock);
break 2;
}
if ($buf == 'sun') {
echo'what are you doing?';
}
$talkback = "Backinformation : '$buf'.\n";
socket_write($msgsock,$talkback,strlen($talkback));
echo "$buf\n";
} while (true);
socket_close($msgsock);
} while (true);
socket_close($sock);
?>
二、client.PHP客户端:
PHP;">
PHP
error_reporting(E_ALL);
//端口111
$service_port = 111;
//本地
$address = 'localhost';
//创建 TCP/IP socket
$socket = socket_create(AF_INET,SOL_TCP);
if ($socket < 0) {
echo "socket创建失败原因: " . socket_strerror($socket) . "\n";
} else {
echo "OK,HE HE.\n";
}
$result = socket_connect($socket,$service_port);
if ($result < 0) {
echo "SOCKET连接失败原因: ($result) " . socket_strerror($result) . "\n";
} else {
echo "OK.\n";
}
//发送命令
$in = "HEAD / HTTP/1.1\r\n";
$in .= "Connection: Close\r\n\r\n";
$out = '';
echo "Send Command..........";
$in = "sun\n";
socket_write($socket,$in,strlen($in));
echo "OK.\n";
echo "Reading Backinformatin:\n\n";
while ($out = socket_read($socket,2048)) {
echo $out;
}
echo "Close socket........";
socket_close($socket);
echo "OK,He He.\n\n";
?>
这两段代码是简单介绍用PHP实现客户端和服务端的通信
具体操作,在DOS下用PHP命令打开SERVER,处于监听状态..
再打开一个DOS窗口,用PHP命令打开CLIENT,会得到服务端的回应....
