PHP4.0.1pl2 Bug? unset() on assoc array inside function

Hello All, I am in the process of porting SourceForge to PHP4. Congratulations on the overall level of compatibility. Frankly, we were stunned that the SF code ran under PHP4 on first try. There are a couple of tiny issues we're running into as I comb through the security of the code under PHP4. I apologize if this is already reported or handled. If anyone feels this is a real bug, I'll go ahead and submit it through your tracker. Anyway: calling unset() on a global associative array inside a function will cause that array to not be global anymore. This is not consistent behavior with calling unset() on a variable inside a function. Here's an example of broken code: $G_USER=array(); function session_setglobals($user_id) { global $G_USER; unset($G_USER); //if I call unset() here - the array //is not global anymore and cannot be //seen outside this function if ($user_id > 0) { $result=db_query("SELECT user_id,user_name FROM user WHERE user_id='$user_id'"); if (!$result || db_numrows($result) < 1) { //echo db_error(); $G_USER = array(); } else { $G_USER = db_fetch_array($result); // echo $G_USER['user_name'].'<BR>'; } } else { $G_USER = array(); } } This code behaves properly (or as I expect it to): unset($USER_IS_SUPER_USER); function user_is_super_user() { global $USER_IS_SUPER_USER; /* members of group_id 1 who are admins have super-user privs site-wide */ if (isset($USER_IS_SUPER_USER)) { return $USER_IS_SUPER_USER; } else { $sql="SELECT * FROM user_group WHERE user_id='". user_getid() ."' AND group_id='1' AND admin_ $result=db_query($sql); if (!$result || db_numrows($result) < 1) { $USER_IS_SUPER_USER=false; return $USER_IS_SUPER_USER; } else { //matching row was found - set and save this knowledge for later $USER_IS_SUPER_USER=true; return $USER_IS_SUPER_USER; } } } Thanks!
