如何让PHP生成Chunked响应 [英] How to make PHP generate Chunked response
本文介绍了如何让PHP生成Chunked响应的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我用谷歌搜索了这个问题，但没有答案。
I googled for this problem but there is no answer for it.
我希望我的PHP脚本在chunked中生成HTTP响应（ http://en.wikipedia.org/wiki/Chunked_transfer_encoding ）。怎么做？
I want my PHP script to generate HTTP response in chunked( http://en.wikipedia.org/wiki/Chunked_transfer_encoding). How to do it?
更新：
我想通了。我必须指定传输编码标头并将其刷新。
Update: I figured it out. I have to specify Transfer-encoding header and flush it.
header("Transfer-encoding: chunked");
flush();
需要冲洗。否则，将生成Content-Length标头。
The flush is necessary. Otherwise, Content-Length header will be generated.
而且，我必须自己制作块。有了辅助函数，它并不难。
And, I have to make chunks by myself. With a helper function, it is not hard.
function dump_chunk($chunk)
{
echo sprintf("%x\r\n", strlen($chunk));
echo $chunk;
echo "\r\n";
}
