python做socket服务端,php做客户端

python server:

#-*-coding=utf-8-*-
from socket import *
#''代表服务器为localhost
myHost = '127.0.0.1'
#在一个非保留端口号上进行监听
myPort = 2011

#设置一个TCP socket对象
sockobj = socket(AF_INET, SOCK_STREAM)
#绑定它至端口号
sockobj.bind((myHost, myPort))
#监听，允许5个连结
sockobj.listen(5)

#直到进程结束时才结束循环
while True:
    #等待下一个客户端连结
    connection, address = sockobj.accept( )
    #连结是一个新的socket
    print 'Server connected by', address
    data = connection.recv(1024)
    if not data: break
    print data
    connection.send('welcome to server'+data)
    connection.close()
    '''
    while True:
        #读取客户端套接字的下一行
        data = connection.recv(1024)
        #如果没有数量的话，那么跳出循环
        if not data: break
        #发送一个回复至客户端
        #print data
        connection.send('welcome to server'+data)
    #当socket关闭时eof
    connection.close()
    '''

php client:

<?php
//确保在连接客户端时不会超时
set_time_limit (0 );

//设置IP和端口号
$address = '127.0.0.1' ;
$port = 2011 ;    //调试的时候，可以多换端口来测试程序！

//创建一个SOCKET
if (($sock = socket_create (AF_INET , SOCK_STREAM , SOL_TCP ))< 0 )
{
echo "socket_create() 失败的原因是:" . socket_strerror ($sock ). "<br>" ;
}

//绑定到socket端口
if (($ret = socket_bind ($sock , $address , $port ))< 0 )
{
echo "socket_bind() 失败的原因是:" . socket_strerror ($ret ). "<br>" ;
}

//开始监听
if (($ret = socket_listen ($sock , 4 ))< 0 )
{
echo "socket_listen() 失败的原因是:" . socket_strerror ($ret ). "<br>" ;
}

do {
if (($msgsock = socket_accept ($sock )) < 0 )
{
echo "socket_accept() failed: reason: " . socket_strerror ($msgsock ) . " \n " ;
break ;
}

//发到客户端
$msg = "<font color=red>欢迎进入服务器！</font><br>" ;
socket_write ($msgsock , $msg , strlen ($msg ));

echo "读取客户端发来的信息<br>" ;
$buf = socket_read ($msgsock , 8192 );

$talkback = "收到的信息: $buf <br>" ;
echo $talkback ;
/* if(socket_write($msgsock, $talkback, strlen($talkback))<0)
     {
      echo "socket_write() failed: reason: " . socket_strerror($msgsock) . "\n";
     }
     else
     {
      echo "发送成功";
     }*/

//echo $buf;
socket_close ($msgsock );
} while (true );

socket_close ($sock );
?>
