服务器端代码：

//确保在连接客户端时不会超时
set_time_limit(0);
$ip = '127.0.0.1';
$port = 1935;
/*
+-------------------------------
* @socket通信整个过程
+-------------------------------
* @socket_create
* @socket_bind
* @socket_listen
* @socket_accept
* @socket_read
* @socket_write
* @socket_close
+--------------------------------
*/
/*----------------以下操作都是手册上的-------------------*/
if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) echo "socket_create() 失败的原因是:".socket_strerror($sock)."\n";
}
if(($ret = socket_bind($sock,$ip,$port)) echo "socket_bind() 失败的原因是:".socket_strerror($ret)."\n";
}
if(($ret = socket_listen($sock,4)) echo "socket_listen() 失败的原因是:".socket_strerror($ret)."\n";
}
$count = 0;
do {
if (($msgsock = socket_accept($sock)) echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n";
echo "等待连接...";

} else {
//发到客户端
