Please post the exact syntax as you did not as the
above will provide a serious parse error. To test
if a value exists, do:
var_dump($_SERVER['DOCUMENT_ROOT']);
Or phpinfo(). Now, going off a guess, try:
include $_SERVER['DOCUMENT_ROOT'] . '/foo.php';
The following will NOT work in 4.3.0 as there
is a bug when using the following syntax:
echo "$_SERVER['DOCUMENT_ROOT']";
echo "Er, $iam['inastringand'] buggy in 4.3.0";
Note that the above gives a parse error in 4.2.3,
a bogus E_NOTICE error in 4.3.0, and will work (no
parse error) in 4.3.1. Now, the following always
works:
echo "{$_SERVER['DOCUMENT_ROOT']}";
echo "So {$i['willalwayswork']} yeah!";
Note: We are specifically talking about using arrays
within strings where the array key is quoted.

P.s. Autoglobals, such a $_SERVER, became available in
PHP in PHP 4.1.0
