fastadmin+phpspreadsheet实现导出和导入

一、在对应的控制层，导入方法

use PhpOffice\PhpSpreadsheet\Reader\Xlsx;  //导入表使用use PhpOffice\PhpSpreadsheet\Reader\Xls;   //导入表使用use PhpOffice\PhpSpreadsheet\Reader\Csv;   //导入表使用use PhpOffice\PhpSpreadsheet\Spreadsheet;  //导出表使用use PhpOffice\PhpSpreadsheet\Cell\Coordinate; //导入表使用

 二、导出方法

public function downloadTemplate()    {        $spreadsheet = new Spreadsheet();        $sheet = $spreadsheet->getActiveSheet();               //设置表头        $sheet->setCellValue('A1', '考生ID');        $sheet->setCellValue('B1', '考生姓名');        $sheet->setCellValue('C1', '报名号');        $sheet->setCellValue('D1', '准考证号');        $sheet->setCellValue('E1', '笔试成绩');        $sheet->setCellValue('F1', '笔试成绩排名');        $sheet->setCellValue('G1', '面试成绩');        $sheet->setCellValue('H1', '面试成绩排名');            //改变此处设置的长度数值        $sheet->getColumnDimension('A')->setWidth(15);        $sheet->getColumnDimension('B')->setWidth(15);        $sheet->getColumnDimension('C')->setWidth(25);        $sheet->getColumnDimension('D')->setWidth(25);        $sheet->getColumnDimension('E')->setWidth(15);        $sheet->getColumnDimension('F')->setWidth(15);        $sheet->getColumnDimension('G')->setWidth(15);        $sheet->getColumnDimension('H')->setWidth(15);         //设置列水平居中        $sheet->getStyle('A')->getAlignment()                        ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);        $sheet->getStyle('B')->getAlignment()                        ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);        $sheet->getStyle('C')->getAlignment()                        ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);        $sheet->getStyle('D')->getAlignment()                        ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);        $sheet->getStyle('E')->getAlignment()                        ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);        $sheet->getStyle('F')->getAlignment()                        ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);        $sheet->getStyle('G')->getAlignment()                        ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);        $sheet->getStyle('H')->getAlignment()                        ->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);        //输出表格        $sheet->setCellValueExplicitByColumnAndRow(1,2,'1',\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);        $sheet->setCellValueExplicitByColumnAndRow(2,2,'张三',\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);        $sheet->setCellValueExplicitByColumnAndRow(3,2,'20230330194812134',\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);        $sheet->setCellValueExplicitByColumnAndRow(4,2,'202300100101',\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);        $sheet->setCellValueExplicitByColumnAndRow(5,2,'95',\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);        $sheet->setCellValueExplicitByColumnAndRow(6,2,'1',\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);        $sheet->setCellValueExplicitByColumnAndRow(7,2,'92',\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);        $sheet->setCellValueExplicitByColumnAndRow(8,2,'1',\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);                $filename = '考生成绩导入模板'.date('ymdhis',time()).'.xlsx';        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');        header('Content-Disposition: attachment;filename="'.$filename.'"');        header('Cache-Control: max-age=0');        $writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');        $writer->save('php://output');        exit;    }

三、导入表格  实现更新数据操作

 public function import()    {        $file = $this->request->request('file');        if (!$file) {            // 参数%s不能为空            $this->error(__('Parameter %s can not be empty', 'file'));         }        $filePath = ROOT_PATH . DS . 'public' . DS . $file;        if (!is_file($filePath)) {            $this->error(__('No results were found'));        }        //实例化reader        $ext = pathinfo($filePath, PATHINFO_EXTENSION);               if (!in_array($ext, ['csv', 'xls', 'xlsx'])) {            $this->error(__('Unknown data format'));        }        if ($ext === 'csv') {            $file = fopen($filePath, 'r');            $filePath = tempnam(sys_get_temp_dir(), 'import_csv');            $fp = fopen($filePath, 'w');            $n = 0;            while ($line = fgets($file)) {                $line = rtrim($line, "\n\r\0");                $encoding = mb_detect_encoding($line, ['utf-8', 'gbk', 'latin1', 'big5']);                if ($encoding !== 'utf-8') {                    $line = mb_convert_encoding($line, 'utf-8', $encoding);                }                if ($n == 0 || preg_match('/^".*"$/', $line)) {                    fwrite($fp, $line . "\n");                } else {                    fwrite($fp, '"' . str_replace(['"', ','], ['""', '","'], $line) . "\"\n");                }                $n++;            }            fclose($file) || fclose($fp);        } elseif ($ext === 'xls') {            $reader = new Xls();        } else {            $reader = new Xlsx();        }        //导入文件首行类型,默认是注释,如果需要使用字段名称请使用name        $importHeadType = isset($this->importHeadType) ? $this->importHeadType : 'comment';        $table = $this->model->getQuery()->getTable();        $database = \think\Config::get('database.database');        $fieldArr = [];        $list = db()->query("SELECT COLUMN_NAME,COLUMN_COMMENT FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = ? AND TABLE_SCHEMA = ?", [$table, $database]);        foreach ($list as $k => $v) {            if ($importHeadType == 'comment') {                $v['COLUMN_COMMENT'] = explode(':', $v['COLUMN_COMMENT'])[0]; //字段备注有:时截取                $fieldArr[$v['COLUMN_COMMENT']] = $v['COLUMN_NAME'];            } else {                $fieldArr[$v['COLUMN_NAME']] = $v['COLUMN_NAME'];            }        }               //加载文件        $updataStudent = []; //批量更新数据               try {            if (!$PHPExcel = $reader->load($filePath)) {                $this->error(__('Unknown data format'));            }            $currentSheet = $PHPExcel->getSheet(0);  //读取文件中的第一个工作表            $allColumn = $currentSheet->getHighestDataColumn(); //取得最大的列号            $allRow = $currentSheet->getHighestRow(); //取得一共有多少行            $maxColumnNumber = Coordinate::columnIndexFromString($allColumn);            $fields = [];            for ($currentRow = 1; $currentRow <= 1; $currentRow++) {                for ($currentColumn = 1; $currentColumn <= $maxColumnNumber; $currentColumn++) {                    $val = $currentSheet->getCellByColumnAndRow($currentColumn, $currentRow)->getValue();                    $fields[] = $val;                }            }                        for ($currentRow = 2; $currentRow <= $allRow; $currentRow++) {                $values = [];                for ($currentColumn = 1; $currentColumn <= $maxColumnNumber; $currentColumn++) {                    $val = $currentSheet->getCellByColumnAndRow($currentColumn, $currentRow)->getValue();                    $values[] = is_null($val) ?
