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 复制代码 代码如下:
error_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 messagen';
$buf = socket_read($msgsock, 8192); //获取客户端发送过来的信息
$talkback = "2.received message:$bufn";
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);

本文实例详细讲述了php中socket的用法,分享给大家供大家参考。具体用法如下:

客户端代码:fsocket.php
复制代码 代码如下:
$fp = fsockopen("127.0.0.1", 10008, &$errno, &$errstr, 10);
if (!$fp) {
echo $errstr . " (". $errno . ")
n";
} else {
$in = "HEAD / http/1.1rn";
$in .= "HOST: localhost rn";
$in .= "Connection: closernrn";
fputs($fp, $in);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}

一、开启socket

phpinfo();查看是否开启了socket扩展,否则在php.ini中开启。

二、服务器端代码的写法

复制代码 代码如下: error_reporting(E_ALL);
set_time_limit(0);
//ob_implicit_flush();

$address = '127.0.0.1';
$port = 10005;
//创建端口
if( ($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";
}

do {
 //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
 $msg = "server send:welcome
";
 socket_write($msgsock, $msg, strlen($msg));
 echo 'read client messagen';
 $buf = socket_read($msgsock, 8192);
 $talkback = "received message:$bufn";
 echo $talkback;
 if (false === socket_write($msgsock, $talkback, strlen($talkback))) {
  echo "socket_write() failed reason:" . socket_strerror(socket_last_error($sock)) ."n";
 } else {
  echo 'send success';
 }
 socket_close($msgsock);
} while(true);
//关闭socket
socket_close($sock);
?>
