Bug description: zlib.output_compression does not ouput HTTP headers when set
to a string value
Description:
------------
When the configuration option 'zlib.output_compression' is set to a
boolean value, output is compressed and the appropriate HTTP headers are
sent. When the option is set to a string like 'true' or 'On', the output
is compressed, but no headers are sent, causing browsers to fail to
interpret the output as compressed.
Reproduce code:
---------------
<?php
ini_set('zlib.output_compression', 'On');
echo 'hello, world';
?>
Expected result:
----------------
The output "hello, world" to be gzip/deflate compressed as appropriate for
Accept-Encoding, and the Content-Encoding and Vary HTTP headers to be set.
Actual result:
--------------
Instead, the output is indeed gzip-compressed, but the Content-Encoding
and Vary headers are not set.
The actual text that the browser prints is:
������ÊHÍÉÉ×Q(Ï/ÊI���ÿÿ�:r«ÿ
���
Note, this works correctly with the an ini_set argument of the boolean
value true. The documentation claims that ini_set should take string
arguments, though. Even if a boolean/integer is required to activate
output compression, the behavior should either be "all on" or "all off".
