Bug or programmer-error?

Dear PHP_friends, I have found a strange behaviour of the "include" function. Here it is . // 1. this works fine include ("../../gps_info/fetch_fields.php"); // 2. this works fine $doc_root=$_SERVER[DOCUMENT_ROOT]; include ("$doc_root"."/pages/gps_info/fetch_fields.php"); // 3. this open the doc fetch_fields.php allright, but variables that have been set outside fetchfields.php are not available within fetch_fields.php $root= 'webserver-2'; include ("$root"."/pages/gps_info/fetch_fields.php"); Does anybody have a clou as to what's wrong here?
