While documenting header_remove() I was experimenting a little bit..
If an "empty" argument is passed to the function (empty string, null,
false,..) the function doesn't do anything, as it checks for
ZEND_NUM_ARGS() rather then the length of string.. thats a doc issue
or bug?
I'd say it's ok, "remove the header with the name ''." That's what it
does.
A header named '' isn't valid in HTTP 1.0 or 1.1 anyway; this is an
error case IMO.
Second, it removes even the X-Powered-By header, is that expected?
Useful for people who don't have control over their expose_php
setting...
Third, it removes session and even cookie headers..
Is that really expected? Just add a big fat warning on the doc page?
It removes all. Should be ok, too, removing the session cookie might
even be considered a "good" feature by some.
Including me! ;)
