Question

Answer 1

I suggest to convert excel to array, clean it from empty elements and then count the number of columns:

protected function getColumnsCheck($file, $col_number) {
        if (strstr($file, ".xls") != false && strstr($file, ".xlsx") != false) {
            $fileType = PHPExcel_IOFactory::identify($file);
            $objReader = PHPExcel_IOFactory::createReader($fileType);
            $objPHPExcel = $objReader->load($file);
            $columns_empty = $objPHPExcel->getActiveSheet(0)->toArray()[0]; 

            $columns = array_filter($columns_empty);

            return ($col_number==count($columns));
        }
        return false;
    }
