How would you edit this to work for certain threads?

how would you edit this to work for admins and forumid 57 and 58?

PHP Code:

0 => iif($bbuserinfo['usergroupid']==6,"$bbuserinfo[username]<!-- auto name hack -->",'{bbusername}'),

Something like :

PHP Code:

if(($bbuserinfo['usergroupid']==6) && ($bbforumid[forumid] == xx))<!-- auto name hack -->",'{bbforumid}'), 


xx = The Forum's forumid...

Not quite sure that will work, but I think it is almost there...
