Using PHP 5.3 + zlib 1.2.3 I *cannot* get compression + headers. I can get no compression, or compression w/o headers, but never "working" compression+headers. I have tried: httpd.conf: php_flag zlib.output_compression On php_admin_flag zlib.output_compression On -> zip + no headers php_flag zlib.output_compression true php_admin_flag zlib.output_compression true -> not zipped In app.php: ini_set('zlib.output_compression', true); ini_set('zlib.output_compression', "On"); -> not zipped ------------------------------------------------------------------------ [2009-07-21 22:50:56] j...@php.net There is something weird going on here, verified it now. Need to investigate more tomorrow. To reproduce on command line: # HTTP_ACCEPT_ENCODING=gzip gdb --arg php-cgi test.php ------------------------------------------------------------------------ [2009-07-21 19:03:10] jflatnes at vt dot edu <?php var_dump(ini_set('zlib.output_compression', 'On')); ?> Results in: string(0) "" (meaning I had no previous setting for zlib.output_compression, I believe) --- I am coming to understand that the string 'On' doesn't behave the same way in ini_set as in an ini file, as mentioned. The issue I see here is that there are two options for zlib compression: zlib.output_compression = false: no compression with no headers. zlib.output_compression = true: compression with appropriate headers. Passing a string to ini_set (other than the string '1') causes a third, undocumented behavior: zlib.output_compression = 'On': compression without the headers. Those three states describe the behavior I'm seeing, and the third state seems like a bug. If 'On' is an invalid setting, shouldn't the compression simply not be activated? Am I thinking about this correctly?) ------------------------------------------------------------------------ [2009-07-21 18:46:33] j...@php.net Try this too: <?php var_dump(ini_set('zlib.output_compression', 'On')); ?> Also note that using "On" or "Off" or such with ini_set() does NOT work like they do when used in php.ini. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
