PHP socket 网络编程实例
如果你对socket理解太模糊，可以做做定位请求的项目，以下是我的经验的结晶，希望对大家有帮助
Php代码
//确保在连接客户端时不会超时
set_time_limit(0);
//设置IP和端口号
$address='127.0.0.1';
$port=2009; //调试的时候，可以多换端口来测试程序!
//创建一个SOCKET
if(($sock=socket_create(AF_INET,SOCK_STREAM,SOL_TCP))<0)
{
echo "socket_create() 失败的原因是:".socket_strerror($sock)."
";
}
//绑定到socket端口
if(($ret=socket_bind($sock,$address,$port))<0)
{
echo "socket_bind() 失败的原因是:".socket_strerror($ret)."
";
}
//开始监听
if(($ret=socket_listen($sock,4))<0)
{
echo "socket_listen() 失败的原因是:".socket_strerror($ret)."
";
}
do {
if (($msgsock = socket_accept($sock)) < 0)
{
echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "/n";
break;
}
//发到客户端
$msg ="欢迎进入服务器!
";
socket_write($msgsock, $msg, strlen($msg));
echo "读取客户端发来的信息
";
$buf = socket_read($msgsock,8192);
$talkback = "收到的信息:$buf
";
echo $talkback;
/* if(socket_write($msgsock, $talkback, strlen($talkback))<0)
{
echo "socket_write() failed: reason: " . socket_strerror($msgsock) . "/n";
}
else
{
echo "发送成功";
}*/
//echo $buf;
socket_close($msgsock);
} while (true);
socket_close($sock);
?>
[php] view plaincopyprint?

CLIENT端
Php代码
error_reporting(E_ALL);
set_time_limit(0);
echo "
TCP/IP Connection
/n";
$service_port = 2009;
$address = "127.0.0.1";
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket < 0)
{
echo "socket_create() failed: reason: " . socket_strerror($socket) . "/n";
}
else
{
echo "OK./n";
}
echo "试图连接 '$address' 端口 '$service_port'...
";
$result = socket_connect($socket, $address, $service_port);
if ($result < 0)
{
echo "socket_connect() failed./nReason: ($result) " . socket_strerror($result) . "/n";
}
else
{
echo "连接OK
";
}
$in = "Hello/r/n";
$in .= "我是Chester/r/n";
$out = '';
$out1='';
if(!socket_write($socket, $in, strlen($in)))
{
echo "socket_write() failed: reason: " . socket_strerror($socket) . "/n";
}
else
{
echo "发送到服务器信息成功!
";
echo "发送的内容为:$in
";
}
while($out = socket_read($socket, 8192))
{
echo "接收服务器回传信息成功!
";
echo "接受的内容为:",$out;
}
echo "关闭SOCKET...
";
socket_close($socket);
echo "关闭OK
";
?>
[php] view plaincopyprint?
error_reporting(E_ALL);
set_time_limit(0);
echo "

$service_port = 2009;
$address = "127.0.0.1";

";
$result = socket_connect($socket, $address, $service_port);
if ($result < 0)

}

echo "关闭SOCKET...

socket_close($socket);
echo "关闭OK
";
?>
先运行server.php
再运行client.php
