ThinkPHP框架导出Excel详细教程，phpOffice——PhpSpreadsheet导入导出

 

 

导出：

案例：

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
use PhpOffice\PhpSpreadsheet\IOFactory;
 
/**
 * [数据导出]
 * @return [type] [description]
 */
function export() {
    $list = [
        [
            'id' => 1,
            'name' => '字段1'
        ],
        [
            'id' => 2,
            'name' => '字段1'
        ]
    ];
 
    $title = ['ID', '名称'];
    // Create new Spreadsheet object
    $spreadsheet = new Spreadsheet();
    $sheet = $spreadsheet->getActiveSheet();
    //表头
    //设置单元格内容
    $titCol = 'A';
    foreach ($title as $key => $value) {
        // 单元格内容写入
        $sheet->setCellValue($titCol . '1', $value);
        $spreadsheet->getActiveSheet()->getColumnDimension($titCol)->setAutoSize(true);
        $titCol++;
    }
    $row = 2; // 从第二行开始
    foreach ($list as $item) {
        $dataCol = 'A';
        // 单元格内容写入
        $sheet->setCellValue($dataCol . $row, $item['id']);$dataCol++;
        $sheet->setCellValue($dataCol . $row, $item['name']);$dataCol++;
 
        $row++;
    }
 
    $name = 'export-'.date('YmdHi');
    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="' . $name . '.xlsx"');
    header('Cache-Control: max-age=0');
    $writer = new Xlsx($spreadsheet);
    $writer->save('php://output');
    //删除清空：
    $spreadsheet->disconnectWorksheets();
 
}

亲测可用--自己的示例：

 

 

 

 

 

 
         public function putinfo(){
           
            $a = Db::name('testpro_dati')->select();
