Similar malfunction here:
<?php
error_reporting(E_ALL);
print_r($_SERVER);
print_r($_ENV);
?>
PHP Notice: Undefined variable: _SERVER in
/var/webservers/cowiki/htdocs/test.php on line 6
PHP Notice: Undefined variable: _ENV in
/var/webservers/cowiki/htdocs/test.php on line 7
Todays CVS, build as CGI on RH6.2

Please try the following script:
<?php
function foo() {
echo $_SERVER;
}
foo();
?>
This script returns "Array". This is the expected behavior.
Now, try this one:
<?php
function foo() {
$bar = '_SERVER';
echo $$bar;
}
foo();
?>
This time, an error is returned:
Notice: Undefined variable: _SERVER on line 4
This is nonsense, of course: As we see in the example above, the
variable should be defined!
