Fastadmin

引用的代码：

use Exception;
use PhpOffice\PhpSpreadsheet\Cell\Coordinate;
use PhpOffice\PhpSpreadsheet\Reader\Xlsx;
use PhpOffice\PhpSpreadsheet\Reader\Xls;
use PhpOffice\PhpSpreadsheet\Reader\Csv;

admin里面继承方法 这是导入的文件

    /**
     * 导入
     */
    public function import()
    {
        $file = $this->request->request('file');
        if (!$file) {
            $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);

            $reader = new Csv();
        } elseif ($ext === 'xls') {
            $reader = new Xls();
        } else {
            $reader = new Xlsx();
        }

开始常用的介绍

 $currentSheet = $PHPExcel->getSheet(0);  //读取文件中的第一个工作表
           
            $allColumn = $currentSheet->getHighestDataColumn(); //取得最大的列号Aj 
            // halt($allColumn);//Aj
            // halt($currentSheet);
            $allRow = $currentSheet->getHighestRow(); //取得一共有多少行 69
            // halt($allRow);//69
            $maxColumnNumber = Coordinate::columnIndexFromString($allColumn);//Aj 
            // halt($maxColumnNumber);//36
            // halt();
            $fields = [];
            // for ($currentRow = 1; $currentRow <= 1; $currentRow++) { //
            //     for ($currentColumn = 1; $currentColumn <= $maxColumnNumber; $currentColumn++) {
            //         $val = $currentSheet->getCellByColumnAndRow($currentColumn, $currentRow)->getValue();
        
             
            //         $fields[] = $val;
            //     }
            // }

      
                //                                          列，行
            $diy_val = $currentSheet->getCellByColumnAndRow(36, 6)->getValue();//////获取某个单元的值
            $diy_val = $currentSheet->getCellByColumnAndRow(1, 8)->getValue();////获取某个单元的值
            halt($diy_val);
