Bug Type: Bug
Bug description:header() / setcookie() / session_start() give bogus warning
Description:
------------
SAPIs that do not support HTTP header(s), give warnings that output has
been already sent like
"Warning: Cannot modify header information - headers already sent by..."
even those APIs do *not* support headers.
There is no use to warn about something that can never happen; There is
nothing to modify; There are no headers that already have been sent.
It might make more sense to warn that this function is useless w/o HTTP
response headers being available.
Compare with headers_sent(), it does differ between SAPIs.
Would be nice to have this a bit more streamlined.
Additionally header() could return FALSE if it failed like setcookie().
Test script:
---------------
In CLI:
<?php
echo "output";
session_start();
setcookie("TestCookie", 'value');
header('X-TestHeader: value');
?>
