PhpSpreadsheet导入导出

PhpSpreadsheet

使用前，使用composer引入PhpSpreadsheet

composer require phpoffice/phpspreadsheet

方法：

1. 导入转数组
2. 导出为文件
3. 导入文件存入数据库

getActiveSheet();

        $highestRow = $worksheet->getHighestRow(); // 总行数
        $highestColumn = $worksheet->getHighestColumn(); // 总列数

        $highestColumnIndex = Coordinate::columnIndexFromString($highestColumn);

        $data = [];
        for ($row = 2; $row <= $highestRow; ++$row) { // 从第二行开始
            $row_data = [];
            for ($column = 1; $column <= $highestColumnIndex; $column++) {
                $row_data[] = $worksheet->getCellByColumnAndRow($column, $row)->getValue();
            }
            $data[] = $row_data;
