Req #60584 [Com]: headers_list() should return in a `$key => $value` fashion

Edit report at https://bugs.php.net/bug.php?id=60584&edit=1 ID: 60584 Comment by: anon at anon dot anon Reported by: toms at mindboiler dot lv Summary: headers_list() should return in a $key => $value fashion Status: Wont fix Type: Feature/Change Request Package: Network related Operating System: CentOS 2.6.18-274.12.1.el5xen PHP Version: Irrelevant Block user comment: N Private report: N New Comment: This could not work. Each sent cookie in an HTTP response has its own Set-Cookie header, and there is no syntax accepted by browsers for combining them into one (separators like commas or semi-colons already have other meanings in the Set-Cookie syntax). Blame Netscape for coming up with that, but 17 years later there's nothing that can be done about it. Example: setcookie('foo', 'bar'); setcookie('abc', '123'); var_dump(headers_list()); Output: array(2) { [0]=> string(19) "Set-Cookie: foo=bar" [1]=> string(19) "Set-Cookie: abc=123" } See also: http://curl.haxx.se/rfc/cookie_spec.html Previous Comments: ------------------------------------------------------------------------ [2011-12-21 15:56:36] cataphract@php.net While I don't think HTTP allows repeated headers, they're common in the wild, so key => value is not an option (maybe if the value was an array, but in any case both options break backwards compatibility). Thank you for the suggestion, anyway. ------------------------------------------------------------------------ [2011-12-21 12:37:53] toms at mindboiler dot lv Changed the summary a little, OS version. ------------------------------------------------------------------------ [2011-12-21 12:34:34] toms at mindboiler dot lv Description: ------------ The function headers_list() returns the headers in a numeric array fashion, although, headers are, AFAIK, always in a Key: Value fashion, therefore, associative array would be a better choice. More on this, header_remove() works by simply passing the key, therefore, in background, headers have their key representation, I suppose. I've made an example function that uses this function, for a header lookup, but ends up in "lots of lines" compared to what could be replaced with one: https://gist.github.com/1505803 P.S. This is my first file in PHP Bugs section, please guide me if I have given not enough information. Test script: --------------- header('Test-Header: A random result'); var_dump(headers_list()); Expected result: ---------------- array(5) { ["X-Powered-By"]=> string(23) "PHP/5.3.3" ["Expires"]=> string(38) "Thu, 19 Nov 1981 08:52:00 GMT" ["Cache-Control"]=> string(77) "no-store, no-cache, must-revalidate, post-check=0, pre-check=0" ["Pragma"]=> string(16) "no-cache" ["Test-Header"]=> string(28) "A random result" } Actual result: -------------- array(5) { [0]=> string(23) "X-Powered-By: PHP/5.3.3" [1]=> string(38) "Expires: Thu, 19 Nov 1981 08:52:00 GMT" [2]=> string(77) "Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0" [3]=> string(16) "Pragma: no-cache" [4]=> string(28) "Test-Header: A random result" } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60584&edit=1
