Bug description:using ob_gzhandler will complain about headers already sent
when no compression
Description:
------------
When using ob_gzhandler with PHP 5.4.0+, PHP will emit warnings after
flushing
more than once (it looks like it's trying to modify headers on each
flush).
This problem didn't exist in PHP 5.3.
Test script:
---------------
<?php
ob_start('ob_gzhandler');
echo "PHP VERSION ".phpversion()."\n";
ob_flush();
flush();
echo "This is confusing:\n";
ob_flush();
flush();
Expected result:
----------------
PHP VERSION 5.5.0-dev
This is confusing:
Actual result:
--------------
PHP VERSION 5.5.0-dev
This is confusing:
Warning: Cannot modify header information - headers already sent by (output
