如何使用PHP实现此方案? [英] How do i implement this scenario using PHP?

问题描述

我正在编写一个使用C2DM的android应用程序.当用户向服务器发送一些消息时，服务器将回复发件人并将该消息转发给网络中的一组其他用户.

问题是，对发件人的答复被延迟，直到将邮件转发给所有其他人为止.这需要很多时间.我希望首先将回复发送回发件人，然后执行转发过程.我怎样才能做到这一点...?如果我可以使用并行处理，如何在PHP中执行...?任何帮助将不胜感激:)

我已经使用过类似的东西

print(json_encode("Inserted Successfully"));//."   ".count($tags)));

while($row = mysql_fetch_row($result))
{
     $id = $row[0];
     sendMessageToUserID($id,"New Question !!",$ques_id,"yyyy");
}

但是，直到执行while循环之后，插入成功"才会发送给发送者.

解决方案

我不知道这是否行得通，但是您可以尝试添加Content-Length:和Connection: close标头，当然还要添加显式刷新的输出.

试试这个

ob_start();
//output
header("Content-Length: ".ob_get_length());
header("Connection: close");
ob_end_flush();
//do other stuff

I am writing an android application which uses C2DM. When a user sends some message to the server, the server replies back to the sender and forwards that message to a set of other users in the network.

The problem is, the reply to the sender is delayed until the message is forwarded to all others. This is taking a lot of time. I want the reply to be sent back to sender first and then perform the forwarding process. How can i achieve this...? If i can use parallel processing, how can i do it in PHP...? Any help would be very much appreciated :)

I have used something like this,

print(json_encode("Inserted Successfully"));//."   ".count($tags)));

while($row = mysql_fetch_row($result))
{
     $id = $row[0];
     sendMessageToUserID($id,"New Question !!",$ques_id,"yyyy");
}

But, here "Inserted Successfully" is not sent to the sender, until after the while loop is executed.

解决方案

I don't know if this will work but you could try adding Content-Length: and Connection: close headers, and of course the explicitly flushing output.

EDIT: try this

ob_start();
//output
header("Content-Length: ".ob_get_length());
header("Connection: close");
ob_end_flush();
//do other stuff
