5 分钟后 php readfile_chunked 失败
这就是我现在所得到的：
$chunksize = 1024*4;
$h = fopen($file, 'rb');
set_time_limit(600);
while(!feof($h)){
echo fread($h, $chunksize);
flush();
}
fclose($h);
我尝试过增加块大小，我尝试过每次迭代重置超时，我尝试过将超时设置为零（最初是 5 分钟），我什至尝试过将flush()放在循环之外，让其自己的缓冲区处理它，每次下载都会在5分钟内终止。有时它是50.2MB，有时它是54.8或介于两者之间的任何东西，所以我知道这不是文件大小。 php_info() 说最大时间是 30 秒，所以我可以将其增加到 300，但仅此而已。
IIS（服务器2003）中是否有某些东西可以覆盖它？
This is what I've got at the moment:
$chunksize = 1024*4;
$h = fopen($file, 'rb');
set_time_limit(600);
while(!feof($h)){
echo fread($h, $chunksize);
flush();
}
fclose($h);
I've tried increasing the chunk size, I've tried resetting the timeout with every iteration, I've tried setting the timeout to zero (it was originally 5min), I even tried putting the flush() outside the loop to let its own buffer take care of it, and every single time the download dies at exactly 5 minutes in. Sometimes it's 50.2MB, sometimes it's 54.8 or anything in between, so I know it's not the file size. php_info() says the maximum time is 30seconds, so somehow I am able to increase it to 300 but that's it.
Is there something in IIS (server 2003) that could be overriding it?

啊，微软 MVP。每当他们说某件事是不可能的时，你就知道这只是挖掘的问题。

我遇到了完全相同的问题..
对于任何人来说，这些解决方案是特定于 Windows IIS 的。
我刚刚花了 2 天尝试了每一种可能的配置，设置了 300 秒来尝试解决问题。
我更改了配置数据库中的 CGITimeout 值，但就我而言，罪魁祸首是 FastCGI ini 文件（位于
c:\windows\system32\inetsrv\fcgiext.ini中）有一个设置 (以秒为单位）：
更改此值并重新启动 IIS。
I was experiencing the EXACT same problem ..
For anyone looking, these solutions are specific to Windows IIS
I just went through 2 days of trying every possible config that had a setting of 300 seconds to try to fix the issue.
I changed the CGITimeout value in the metabase, but in my case the culprit turned out to be the FastCGI ini file (located in
c:\windows\system32\inetsrv\fcgiext.ini)There's a setting (in seconds):
Change this value and restart IIS.
