基于php socket(fsockopen)的应用实例分析
分类：PHP作者：编程之家
fsockopen函数能够运用，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
<div class="codetitle">
<a style="CURSOR: pointer" data="49978" class="copybut" id="copybut49978" onclick="doCopy('code49978')"> 代码如下: <div class="codebody" id="code49978">
<?
PHPerror_reporting(E_ALL);
set_time_limit(0);
$address = '127.0.0.1';
$port = 10008;
//创建端口
if (($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) === false) {
echo "socket_create()
Failed:reason:" . socket_strerror(socket_last_error()) . "\n";
}
//绑定
if (socket_bind($sock,$address,$port) === false) {
echo "socket_bind()
Failed :reason:" . socket_strerror(socket_last_error($sock)) . "\n";
}
//监听
if (socket_listen($sock,5) === false) {
echo "socket_bind()
Failed :reason:" . socket_strerror(socket_last_error($sock)) . "\n";
}
while (true) {
//得到
一个链接if (($msgsock = socket_accept($sock)) === false) {
echo "socket_accepty()
Failed :reason:"
.socket_strerror(socket_last_error($sock)) . "\n";
break;
}
//welcome 发送到客户端
$msg = "1.
server send:welcome";
socket_write($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);
：fsocket.
