Re: [PHP] Exec as user From: charlesk (charlesk <email protected>)
Date: 12/28/01

I tried echo %PATH% > test.txt and both the webpage and the dos prompt echo the correct path information. This shows that a batch file executed by php can access the system vars. They have a diffence only in accessing the %USERNAME% variable. Could this be indicative that it is running as the system user? If so how do I change that?

Try doing this

<?
     echo '<pre>';
     print_r(array($HTTP_SERVER_VARS,$HTTP_ENV_VARS));
     echo '</pre>';
?>

And see if the information you want is in there anywhere.
