the reason why i dropped check for $_SERVER/$_ENV

no need for this function-call-overhead for checking this arrays - as

getenv can not work when something is _only_
a server variable but not
in environment.
What do you exactly mean with 'server' and
'environment'?
no $_SERVER variable is in $_ENV
and variable not in _ENV is not returned by getenv.
Just try this code:
foreach($_SERVER as $key => $val) {
if ($val != getenv($key)) {
echo "$key differs from _SERVER\n";
echo "$key = $val / " . getenv($key) . "\n";
}
}
foreach($_ENV as $key => $val) {
if ($val != getenv($key)) {
echo "$key differs from _ENV\n";
echo "$key = $val / " . getenv($key) . "\n";
}
}
Most likely some variables from _SERVER are not available throught
getenv:
SCRIPT_NAME differs from _SERVER
SCRIPT_NAME = test.php /
SCRIPT_FILENAME differs from _SERVER
SCRIPT_FILENAME = test.php /
this booth works for me with getenv() (egual in getenv() end $_SERVER),
wired
PHP_* seems clear, as they are not really 'environment' variables
