Bug description:flush() disables compression from ob_gzhandler
Description:
------------
Hi,
Consider the test script.
One might expect to see: Content-Encoding: gzip in the response headers,
but it's not there. If however you comment out that flush() compression is
applied.
As a small amount of background, I work on two tools that help display data
from the xhprof extension. They both include flush(); ignore_user_abort();
before doing work to store the profiling information in attempt to have as
little impact on the user as possible. Clearly flush() wasn't the safe
command I thought it was, as it's having a large affect on the application
I'm profiling.
I'm prepared to write this up in the documentation, but I don't really
think this is expected behavior.
Test script:
---------------
<?php
ob_start('ob_gzhandler');
phpinfo();
flush();
Expected result:
----------------
output compressed
Actual result:
--------------
no compression
