thinkphp Operation Phpexcel Problem

First, thinkphp introduced Phpexcel to/thinkphp/library/vendor/

Second, reference in the controller

    Public Function Get_detail ()    {        Vendor ("Phpexcel.phpexcel", "', '. php ');        $obj = new \phpexcel;        $filename = self::file_dir. ' My_data.xls ';        try {            $inputFileType = \phpexcel_iofactory::identify ($filename);            $objReader = \phpexcel_iofactory::createreader ($inputFileType);            $objPHPExcel = $objReader->load ($filename);        } catch (Exception $e) {die            (' Loading file error: '. PathInfo ($filename, Pathinfo_basename). ': '. $e->getmessage ());        }        $sheet = $objPHPExcel->getsheet (0);        $highestRow = $sheet->gethighestrow ();        $highestColumn = $sheet->gethighestcolumn ();        for ($i =1; $i <= $highestRow; $i + +) {             $rowData [] = $sheet->rangetoarray ("a{$i}:{$highestColumn} {$i}", NULL, True,false);        }        echo Json_encode ($rowData);    }

For the first time in use, encountered some pits, sharing the next

1.Vendor ("Phpexcel.phpexcel", "', '. php '), can be Vendor (" Phpexcel.phpexcel "); Suffix is subject to availability

2. To attach great importance to namespace issues, be sure to add a backslash ' \
