问题描述

我想了解如何通过 PHP读取 excel 文件.我的具体用例是在 Yii 中使用 PHPExcel.

I would like to find out how to read an excel file using via PHP. My specific use case is using PHPExcel from within Yii.

我已经学习了许多教程，但我总是卡在一个地方:ZipArchive::getFromName():无效或未初始化的 Zip 对象".我已经添加了扩展、加载器等，但似乎没有任何效果.有没有办法解决?还是我需要另一个图书馆?这是我的控制器中的代码.

I have followed numerous tutorials and I am always stuck at one point: "ZipArchive::getFromName(): Invalid or unitialized Zip object". I have added the extensions, loader, etc. but nothing seems to be working. is there any way around this? or do I need to get another library? Here is the code in my controller.

Yii::import('application.vendors.PHPExcel.PHPExcel',true);
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load('c:\cctv.xls'); //$file --> your filepath and filename
$objWorksheet = $objPHPExcel->getActiveSheet();
$highestRow = $objWorksheet->getHighestRow(); // e.g. 10
$highestColumn = $objWorksheet->getHighestColumn(); // e.g 'F'
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn); // e.g. 5
echo '<table>' . "\n";
for ($row = 2; $row <= $highestRow; ++$row) {
  echo '<tr>' . "\n";
  for ($col = 0; $col <= $highestColumnIndex; ++$col) {
    echo '<td>' . $objWorksheet->getCellByColumnAndRow($col, $row)->getValue() . '</td>' . "\n";
  }
  echo '</tr>' . "\n";
}
echo '</table>' . "\n";

这是详细的错误:

C:\wamp\www\example\protected\vendors\PHPExcel\PHPExcel\Reader\Excel2007.php(272)

}
 public function _getFromZipArchive(ZipArchive $archive, $fileName = '')
 {
     // Root-relative paths
     if (strpos($fileName, '//') !== false)
     {
         $fileName = substr($fileName, strpos($fileName, '//') + 1);
     }
     $fileName = PHPExcel_Shared_File::realpath($fileName);

     // Apache POI fixes
     $contents = $archive->getFromName($fileName);
     if ($contents === false)
     {
         $contents = $archive->getFromName(substr($fileName, 1));
     }

     /*
     if (strpos($contents, '<?xml') !== false && strpos($contents, '<?xml') !== 0)
     {
         $contents = substr($contents, strpos($contents, '<?xml'));
     }
     var_dump($fileName);
     var_dump($contents);

推荐答案

您似乎将 PHPExcel 设置为显式使用 2007 格式，但您正在尝试打开 XLS 文件.虽然我不是 100% 确定，但我会猜测 zip 错误是因为它试图解压缩 XLS 文件，这将失败，因为它没有被压缩.

It looks like you set PHPExcel to explicitly use the 2007 format, but you're trying to open an XLS file. While I'm not 100% sure, I'm going to guess the zip error is because it's trying to unzip the XLS file, and that's going to fail as it's not zipped.

php zip 扩展似乎正在工作，因为错误来自扩展 - 无效或未初始化的 Zip 对象.我的猜测是您得到了一个无效的 Zip 对象，因为您没有处理 zip 文件.

The php zip extension appears to be working, as the error is from the extension - Invalid or unitialized Zip object. My guess is that you're getting an invalid Zip object since you're not dealing with a zip file.

如果您尝试打开 XLS 文件，您可能需要:

If you're trying to open an XLS file, you probably want:

$objReader = PHPExcel_IOFactory::createReader('Excel5');

或者，您可以删除显式模式，并仅依赖于自动文件类型解析，例如:

Alternatively, you could remove the explicit mode, and just rely upon the automatic file type resolution, e.g.:

$objPHPExcel = PHPExcel_IOFactory::load("c:\cctv.xls");  // Remove the createReader line before this
