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:

PHP_SELF differs from _SERVER
PHP_SELF = test.php /
SCRIPT_NAME differs from _SERVER
SCRIPT_NAME = test.php /
SCRIPT_FILENAME differs from _SERVER
SCRIPT_FILENAME = test.php /
PATH_TRANSLATED differs from _SERVER
PATH_TRANSLATED = test.php /
REQUEST_TIME differs from _SERVER
REQUEST_TIME = 1144763136 /
