php中socket的用法详解,phpsocket详解

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:

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 message\n';
 $buf = socket_read($msgsock, 8192);
 $talkback = "received message:$buf\n";
 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);
?>

服务器端需要在cli模式是执行,有可能cli模式下php.ini文件载入的不一样

可以像如下输出:

这时候在zhoxh目录下就有个tem.text文件。查看 Configuration File (php.ini) Path => C:\WINDOWS 。不是我的php.ini 文件,这说明调用的php.ini文件时错误的。这时候我们要指定php.ini文件命令如下

注意的是我的php可以直接执行时配置了环境变量。

三、客户端

复制代码 代码如下:

//error_reporting(E_ALL);
echo "

tcp/ip connection

\n";
$service_port = 10005;
$address = '127.0.0.1';

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
 echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
} else {
 echo "OK. \n";
}

echo "Attempting to connect to '$address' on port '$service_port'...";
$result = socket_connect($socket, $address, $service_port);
if($result === false) {
 echo "socket_connect() failed.\nReason: ($result) " . socket_strerror(socket_last_error($socket)) . "\n";
} else {
 echo "OK \n";
}
$in = "HEAD / http/1.1\r\n";
$in .= "HOST: localhost \r\n";
$in .= "Connection: close\r\n\r\n";
$out = "";
echo "sending http head request ...";
socket_write($socket, $in, strlen($in));
echo  "OK\n";

echo "Reading response:\n\n";
while ($out = socket_read($socket, 8192)) {
 echo $out;
}
echo "closeing socket..";
socket_close($socket);
echo "ok .\n\n";


 
执行结果如下:
server:

client:

希望本文所述对大家的PHP程序设计有所帮助。

socket在php主要是什作用?用在什方面?

一般用在和服务器的交互,传是数据之类的!
 

php的socket编程在项目中用的多

Sockets在PHP中是没有充分利用的功能。今天你将看到产生一个能使用客户端连接的服务器,并在客户端使用socket进行连接,服务器端将详细的处理信息发送给客户端。
当你看到完整的socket过程,那么你将会在以后的程序开发中使用它。这个服务器是一个能让你连接的HTTP服务器,客户端是一个Web浏览器,这是一个单一的 客户端/服务器 的关系。
