laravel excel我如何取消子弹时，我做getcell

Excel::load($path, function($reader) { $sheet = $reader->getSheetByName('nameofsheet'); $cellvalue = $sheet->getCell('B10'); //cell with a bullet (bullet and text of cell) $echo $cellvalue; //display (Ÿ text of cell) display Ÿ instead of bullet and i don't want this character });
