致命错误：Class＆＃39; PHPExcel_IOFactory＆＃39;在phpExel中找不到

Question

我使用下面的代码，所有PHPexcel库数据都在下面的图片中。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<!-- I want to change the "data-value" value here (it's a meter gauge lots of JS -->

<div class="gauge" id="guagechanger" data-plugin="gauge" data-value="1" data-min-value="1" data-max-value="10" data-stroke-color="#f978a6">
         <div class="gauge-label"></div>
         <canvas width="200" height="150"></canvas>
</div>

<!-- my plus and minus buttons -->

<button type="button" class="btn btn-floating btn-danger value-control" data-action="minus" data-target="guagechanger"><i class="icon wb-minus" aria-hidden="true"></i></button>

<button type="button" class="btn btn-floating btn-danger value-control" data-action="plus" data-target="guagechanger"><i class="icon wb-plus" aria-hidden="true"></i></button>

我想阅读NIB.xlsx文件，我已阅读此help link。

但是，当我运行PHP脚本时，收到以下错误：

  

致命错误：Class＆＃39; PHPExcel_IOFactory＆＃39;在untitled-2.php中的phpExcel中找不到

Answer 1

我想您忘记包含PHPExcel文件了 在代码的开头添加此行

require 'PHPExcel/Classes/PHPExcel.php';

别忘了添加文件夹的路径，将其放在不同的文件夹中

Answer 2

尝试官方文档中的一些简单示例时，我也收到此错误。我正在使用随Composer安装的PHPOffice。如果在本地安装，则概念应相同。错误基本上是路径问题，即脚本不知道可以在哪里找到IOFactory。这是我找到的完整的工作解决方案。

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$styleArray = [
    'font' => [
        'bold' => true,
    ],
    'alignment' => [
        'horizontal' => \PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_RIGHT,
    ],
    'borders' => [
        'top' => [
            'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THIN,
        ],
    ],
    'fill' => [
        'fillType' => \PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID,
        'color' => [
            'argb' => 'FFA0A0A0',
        ]
    ],
];

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Hello World !');
$spreadsheet->getActiveSheet()->getStyle('A3:m3')->applyFromArray($styleArray);


// Redirect output to a client's web browser (Xlsx)
header('Content-Type: application/vnd.openxmlformats- officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="webstats.xlsx"');
header('Cache-Control: max-age=0');

$writer = PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');
exit;

我将在线示例中的这一行更改为

$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');

对此

$writer = PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');

并且IO错误已解决
