Can someone explain what this is, either in the
context below or just in general. I do not understand
what this statement means?

10      var $TRAIL = array();
129             while ( $row = mysql_fetch_array($results))
130             {
131                     $trail = $this->TRAIL;
132                     $count = count($trail);
133                     $trail[$count] = $row;
134                     $this->TRAIL = $trail;
135                     $id = $row["CatParent"];
136                     $this->get_Parents($id);
137             }

sql query is "SELECT CatID,CatParent,CatName from
Categories where CatID = $CatID";
