php socket(fsockopen)函数使用代码

php socket(fsockopen)函数的应用实例

使用fsockopen函数，首先要开启php.ini中的allow_url_open=on;

fsockopen是对socket客户端代码的封装，该函数中封装了socket_create(),socket_connect()。

服务器端代码：server.php

server send:welcome
";
socket_write($msgsock, $msg, strlen($msg)); //返回信息给客户端
echo "read client message\n";
$buf = socket_read($msgsock, 8192); //获取客户端发送过来的信息
$talkback = "2.received message:$buf\n";
echo $talkback;
if (false === socket_write($msgsock, $talkback, strlen($talkback))) { //返回信息给客户端
	echo "socket_write() failed reason:" . socket_strerror(socket_last_error($sock)) ."\n";
} else {
	echo "send success";
}
socket_close($msgsock);
}
socket_close($sock);

客户端代码：fsocket.php

n";
} else {
$in = "HEAD / http/1.1\r\n";
$in .= "HOST: localhost \r\n";
$in .= "Connection: close\r\n\r\n";
fputs($fp, $in);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
