由于PHPExcel已经不再维护,PhpSpreadsheet是PHPExcel的下一个版本。PhpSpreadsheet是一个用纯PHP编写的库,并引入了命名空间,PSR规范等。这里简单介绍下PhpSpreadsheet的导入导出功能。

1、安装

使用composer安装:
composer require phpoffice/phpspreadsheet

GitHub下载:https://github.com/PHPOffice/PhpSpreadsheet

2、excel文件导出

    // 命名空间引入
    use PhpOffice\PhpSpreadsheet\IOFactory;
    use PhpOffice\PhpSpreadsheet\Spreadsheet;

    /**
     * @title export 导出
     */
    public function export() {
        $data  = [
            ['title1' => '111', 'title2' => '222'],
            ['title1' => '111', 'title2' => '222'],
            ['title1' => '111', 'title2' => '222']
        ];
        $title = ['标题1', '标题2'];
        array_unshift($data, $title);

        // Create new Spreadsheet object
        $spreadsheet = new Spreadsheet();
        $sheet       = $spreadsheet->getActiveSheet()->setTitle('工作表标题');

        foreach ($data as $k => $item) {
            $column = 1;
            foreach ($item as $value) {
            // 因不想定义 A…  一大串大写字母 所以使用数字单元格坐标设置单元格值。
                $sheet->setCellValueByColumnAndRow($column, $k + 1, $value);
                $column++;
            }
        }

        // Redirect output to a client’s web browser (Xlsx)
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="01simple.xlsx"');
        header('Cache-Control: max-age=0');
        // If you're serving to IE 9, then the following may be needed
        header('Cache-Control: max-age=1');
        // If you're serving to IE over SSL, then the following may be needed
        header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');              // Date in the past
        header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
        header('Cache-Control: cache, must-revalidate');               // HTTP/1.1
        header('Pragma: public');                                      // HTTP/1.0
        $writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
        $writer->save('php://output');
        exit;
    }

3、读取excel文件内容

/**
    // 命名空间引入
    use PhpOffice\PhpSpreadsheet\IOFactory;
    
    
     * @title  readExcel 读取excel文件内容
     * @return array
     */
    public function readExcel() {
        $inputFileName = './test.xlsx';
        $spreadsheet   = IOFactory::load($inputFileName);
        //  toArray() 具体参数参考官方文档
        $sheetData = $spreadsheet->getActiveSheet()->toArray(null, true, true, true);
        return $sheetData;
    }
