php flush() are not effective.

[Ken Chen]

hi Shri,

Thanks a lot! It works.

I change the nginx configuration to:

fastcgi_buffer_size 4k;
gzip  off;

And PHP script:

<?php

ob_flush();
echo The first line<br />";
flush();
sleep(2);

for ($i=10; $i>0; $i--)
{
    echo $i . "<br />";
    echo str_repeat(" ",4096);
    ob_flush();
    flush();
    sleep(1);
}
ob_end_flush();
?>

But how do you implement them to the productive server?

Set 'zlib.output_compression = On' in php.ini, and only compress static
content in nginx.conf ?


Regards,
Ken
