1.导出表格

<?php
    namespace app
    # 给类文件的命名空间起个别名
    use PhpOffice\PhpSpreadsheet\Spreadsheet;
    # Xlsx类 将电子表格保存到文件
    use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
    # 实例化 Spreadsheet 对象
    $spreadsheet = new Spreadsheet();
    # 获取活动工作薄
    $sheet = $spreadsheet->getActiveSheet();

    $sheet->setCellValue('A1','10');
    $sheet->setCellValue('B1','15');
    $sheet->setCellValue('C1','20');
    $sheet->setCellValue('D1','25');
    $sheet->setCellValue('E1','30');
    $sheet->setCellValue('G1','35');
    $sheet->setCellValue('A2', '总数：');
    $sheet->setCellValue('B2', '=SUM(A1:G1)');
    $sheet->setCellValue('A3', '平均数：');
    $sheet->setCellValue('B3', '=AVERAGE(A1:G1)');
    $sheet->setCellValue('A4', '最小数：');
    $sheet->setCellValue('B4', '=MIN(A1:G1)');
    $sheet->setCellValue('A5', '最大数：');
    $sheet->setCellValue('B5', '=MAX(A1:G1)');
    $sheet->setCellValue('A6', '最大数：');
    $sheet->setCellValue('B6', '\=MAX(A1:G1)');    // 使用转义字符
    // 批量赋值
    $sheet->setCellValue('A1','ID');
    $sheet->setCellValue('B1','姓名');
    $sheet->setCellValue('C1','年龄');
    $sheet->setCellValue('D1','身高');
    $sheet->fromArray(
        [
            [1,'欧阳克','18岁','188cm'],
            [2,'黄蓉','17岁','165cm'],
            [3,'郭靖','21岁','180cm']
        ],
        3,
        'A2'
    );
    // 合并单元格 合并后，赋值只能给A1，开始的坐标。
    $sheet->mergeCells('A1:B5');
    $sheet->getCell('A1')->setValue('欧阳克');
    
    # Xlsx类 将电子表格保存到文件
    $writer = new Xlsx($spreadsheet);
    $writer->save('1.xlsx');
    
   // 客户端文件下载
    header('Content-Type:application/vnd.ms-excel');
    header('Content-Disposition:attachment;filename=1.xls');
    header('Cache-Control:max-age=0');
    $writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xls');
    $writer->save('php://output');

2.读取表格

<?php
    namespace app;
    # 创建读操作
    $reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader('Xlsx');
    # 打开文件、载入excel表格
    $spreadsheet = $reader->load('1.xlsx');
    # 获取活动工作薄
    $sheet = $spreadsheet->getActiveSheet();

    # 获取 单元格值 和 坐标
    $cellC1 = $sheet->getCell('B2');
    echo '值: ', $cellC1->getValue(),PHP_EOL;
    echo '坐标: ', $cellC1->getCoordinate(),PHP_EOL;

    $sheet->setCellValue('B2','欧阳锋');

    # 获取 单元格值 和 坐标
    $cellC2 = $sheet->getCell('B2');
    echo '值: ', $cellC2->getValue(),PHP_EOL;
    echo '坐标: ', $cellC2->getCoordinate();

3.导入功能

<?php
    $file = $_FILES['file']['tmp_name'];
    # 载入composer自动加载文件
    require 'vendor/autoload.php';
    # 载入方法库
    require 'function.php';

    # 创建读操作
    $reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader('Xlsx');
    # 打开文件、载入excel表格
    $spreadsheet = $reader->load($file);
    # 获取活动工作薄
    $sheet = $spreadsheet->getActiveSheet();

    # 获取总列数
    $highestColumn = $sheet->getHighestColumn();
    # 获取总行数
    $highestRow = $sheet->getHighestRow();

    # 列数 改为数字显示
    $highestColumnIndex = \PhpOffice\PhpSpreadsheet\Cell\Coordinate::columnIndexFromString($highestColumn);
    $log = [];
    for($a=2;$a<$highestRow;$a++){
        $title = $sheet->getCellByColumnAndRow(1,$a)->getValue();
        $cat_fname = $sheet->getCellByColumnAndRow(2,$a)->getValue();
        $cat_name = $sheet->getCellByColumnAndRow(3,$a)->getValue();
        $price = $sheet->getCellByColumnAndRow(4,$a)->getValue();
        $img = $sheet->getCellByColumnAndRow(5,$a)->getValue();

        $cat_fid = find('shop_cat','id','name="'.$cat_fname.'"');
        $cat_id = find('shop_cat','id','name="'.$cat_name.'"');
        $data = [
            'title' => $title,
            'cat_fid' => $cat_fid['id'],
            'cat_id' => $cat_id['id'],
            'price' => $price,
            'img' => $img,
            'add_time' => time(),
        ];
        $ins = insert('shop_list',$data);
        if($ins){
            $log[] = '第'.$a.'条，插入成功';
        }else{
            $log[] = '第'.$a.'条，插入失败';
        }
    }
    echo json_encode(['code'=>0,'msg'=>'成功','data'=>$log]);
