本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，具有一定的参考价值，感兴趣的小伙伴们可以参考一下。
一、server.php服务端：
<?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
error_reporting(e_all);
//端口111
$service_port = 111;
//本地
$address = 'localhost';
//创建 tcp/ip socket
$socket = socket_create(af_inet, sock_stream, sol_tcp);
if ($socket < 0) {
echo "socket创建失败原因: " . socket_strerror($socket) . "\n";
} else {
echo "ok，he he.\n";
}
$result = socket_connect($socket, $address, $service_port);
if ($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....
