PHP基于socket实现的简单客户端和服务端通讯功能示例

<?php set_time_limit(0); $host="localhost"; $port=1001; //创建一个连接 $socket=socket_create(af_inet,sock_stream,sol_tcp)or die("cannot create socket\n"); //绑定socket到端口 $result=socket_bind($socket,$host,$port) or die("cannot bind port to socket\n"); //开始监听这个端口 $result=socket_listen($socket,4) or die("could not set up socket listen\n"); //接受连接，另一个socket来处理通信 $msgsock=socket_accept($socket) or die("cannot accept incoming connection\n"); if($msgsock){ echo date("y-m-d h:i:s d a"); } //读取客户端发送过来的信息 $input=socket_read($msgsock,1024) or die("cannot read input\n"); $input=trim($input); $output=strrev($input)."顺序反过来了吧\n"; //对接收到的信息进行处理，然后返回到客户端 socket_write($msgsock,$output,strlen($output)) or die("cannot write"); //关闭socket连接 socket_close($msgsock); socket_close($socket); ?>

<?php set_time_limit(0); $host="localhost"; $port=1001; //创建一个socket $socket=socket_create(af_inet,sock_stream,sol_tcp)or die("cannot create socket\n"); $conn=socket_connect($socket,$host,$port) or die("cannot connect server\n"); if($conn){echo "client connect ok!";} socket_write($socket,"hello world!") or die("cannot write data\n"); $buffer=socket_read($socket,1024,php_normal_read); if($buffer){ echo "response was:".$buffer."\n"; } socket_close($socket); ?>
