";} / / current location navigation, recursively query parent column function findparent ($classid) {global $empire,$dbtbpre; $query=" select classname,bclassid,classpath from {$dbtbpre} enewsclass where classid= ". $classid; $sql=$empire- > query ($query) While ($ritual empires-> fetch ($sql)) {findparent ($r [bounded]); echo ">". $r [classname]. ";}}
