php socket 最简单实例

服务端：

server.php

<?php
$sendStr="我是服务端参数2";  
$socket=socket_create(AF_INET,SOCK_STREAM,getprotobyname("tcp"));  //建立通道
socket_bind($socket,"localhost",1234);   //绑定要监听的端口
if(socket_listen($socket)){   //监听端口
$receiveSocket=socket_create(AF_INET,SOCK_STREAM,getprotobyname("tcp"));   
$receiveSocket=socket_accept($socket);
socket_write($receiveSocket,$sendStr,strlen($sendStr));   //写如通道
$receiveStr="";
$receiveStr=socket_read($receiveSocket,1024);  //读取通道
echo "客户端传入:".$receiveStr;
}
socket_close($receiveSocket);
socket_close($socket);
?>

客户端：

client.php

<?php
 $sendStr="客户端传递参数为1";
 $socket=socket_create(AF_INET,SOCK_STREAM,getprotobyname("tcp"));  //建立通道

 if(socket_connect($socket,"localhost",1234)){  //连接通道
  $receiveStr="";
  $receiveStr=socket_read($socket,1024); //读取服务端返回参数
  echo "服务端返回参数:".$receiveStr;  
  socket_write($socket,$sendStr,strlen($sendStr));  //参数写入通道中
 }
 socket_close($socket); 
?>

先运行，server.php  再运行client.php

建议在命令行下运行该代码；
