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" } PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

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.htmlFor repeated headers you can always use multidimensional array. It wouldn't be deeper than two levels anyways. Like: 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" ["Set-Cookie"]=> array(2) { [0]=> string(7) "foo=bar" [1]=> string(7) "abc=123" } } Or, since Cookies are pretty predictable, associate them to keys too, or headers_list($flags) and add specific headers flags. But, yes... The evilness of backwards compatibility, that ruins future functionality.
