将数组导出到 PHPExcel 生成数组到字符串的转换错误

Exporting array to PHPExcel producing array to string conversion error

我正在使用 Codeigniter 和 PHPexcel尝试将数据库结果中的数组写入 excel 工作表。

我有一个由以下数据组成的数组。

Array
(
[0] => stdClass Object
    (
        [ORDER] => 12334
        [DATE] => 2015-10-05
        [TEXT] => TEST
        [TIME] => 06:03:03
        [STATUS] => 1

    )

[1] => stdClass Object
    (
        [ORDER] => 99999
        [DATE] => 2015-10-05
        [TEXT] => TEST2
        [TIME] => 08:03:03
        [STATUS] => 0
    )

)

当我尝试使用 phpexcel 将数据写入 excel 文件时,出现 class stdClass 的对象无法转换为字符串错误。 我希望 excel 文件的列名称为 OrderDateTextTime 状态,并在行中填充相应的值。

这是我当前的代码

$this->load->library('excel');
    $this->excel->setActiveSheetIndex(0);
    $this->excel->getActiveSheet()->setTitle('test worksheet');
    $this->excel->getActiveSheet()->fromArray($ordersArray, NULL, 'A1');

    $filename='export.xls'; //save our workbook as this file name
    header('Content-Type: application/vnd.ms-excel'); //mime type
    header('Content-Disposition: attachment;filename="'.$filename.'"'); //tell browser what's the file name
    header('Cache-Control: max-age=0'); //no cache

    //save it to Excel5 format (excel 2003 .XLS file), change this to 'Excel2007' (and adjust the filename extension, also the header mime type)
    //if you want to save it as .XLSX Excel 2007 format
    $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');  
    //force user to download the Excel file without writing it to server's HD
    $objWriter->save('php://output');

我认为这是数组中对象的问题,但我不确定如何让它工作。

您需要先将对象转换为数组,使其成为二维数组:

array_walk(
    $ordersArray,
    function (&$row) {
        $row = (array) $row;
    }
);
$this->excel->getActiveSheet()->fromArray($ordersArray, NULL, 'A1');
