MySQL Help - How Would I Optimize this?

[Modin]

Like so

switch ($bbuserinfo['usergroupid']) {
case 0:
   eval("\$unregwelcomemessage = \"".gettemplate('forumhome_unregmessage')."\";"); 
   break;
case 3:
   eval("\$nonactivatedmessage = \"".gettemplate('awaitconfmessage')."\";");
   break;
case 4:
   eval("\$activatedwaitingapproval = \"".gettemplate('awtngadmapprvl')."\";");
}

//edit: whooops, had userid instead of usergroupid
