I don't appear to be able to use this variable in an include directive because the variable is empty: include "$_SERVER['DOCUMENT_ROOT'] Do I have the syntax incorrect?

Please post the exact syntax as you did not as the above will provide a serious parse error.

include "$_SERVER['DOCUMENT_ROOT']/visit_db.php"; I am using 4.3.0, there is no release later.

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