php的socket服务端监听与客户端访问实例脚本

服务器端脚本：

<?php

$host="127.0.0.1";

$port=1232;

set_time_limit(0);

//开启套接字监听过程

$socket=socket_create(AF_INET,SOCK_STREAM,6) or die("Could not create socket\n");

$result=socket_bind($socket,$host,$port) or die("Could not bind to socket\n");

$result=socket_listen($socket,3) or die("Could not set up socket listener\n");

//开启连接请求接受过程

//while(true){ //如果需要持续性监听，就在此开启死循环

$spawn=socket_accept($socket) or die("Could not accept incoming connection\n");

$input=socket_read($spawn,10240) or die("Could not read input\n");

$input=trim($input);

$output=$input ."\n";

socket_write($spawn,$output,strlen($output)) or die("Could not write output\n");

socket_close($spawn);

//}

socket_close($socket);

客户端脚本：

<?php

$host="127.0.0.1";

$port=1232;

$socket=socket_create(AF_INET,SOCK_STREAM,6) or die("Could not create socket\n");

$conn = socket_connect ($socket, $host, $port);//连接服务器

socket_write ($socket, 'wocao', 5);//传输数据

$output=socket_read($socket,10240) or die("Could not read input\n");

echo $output;

socket_close ($socket);
