Bug description: apache_response_headers() does not include duplicate headers
Description:
------------
When multiple response headers with the same name are set using
header(..., false), only the last value is returned by
apache_response_headers().
apache_response_headers() returns an associative array, so it cannot have
multiple entries for the same header name. However, according to section
4.2 of RFC 2616, multiple headers with the same name may be combined into
one comma-separated header.
It MUST be possible to combine the multiple header fields into
one "field-name: field-value" pair, without changing the semantics
of the message, by appending each subsequent field-value to the
first, each separated by a comma.
I suggest that apache_response_headers() does this, i.e. combines multiple
headers with comma.
Reproduce code:
---------------
header('Foo: 1');
header('Foo: 2', false);
header('Foo: 3', false);
var_dump(apache_response_headers());
Expected result:
----------------
array(2) {
["X-Powered-By"]=>
string(9) "PHP/5.2.5"
["Foo"]=>
string(1) "1,2,3"
}
Actual result:
--------------
array(2) {
["X-Powered-By"]=>
string(9) "PHP/5.2.5"
["Foo"]=>
string(1) "3"
}
