【问题标题】:PHP Read xlsx Excel 2007 filePHP 读取 xlsx Excel 2007 文件
【发布时间】:2010-03-27 05:10:50
【问题描述】:

我正在使用 oleread 读取上传的 xls 文件。但我无法读取以 excel-2007 格式保存的 xlsx 文件。有人可以帮助我如何在 PHP 中读取 xlsx 文件。

【问题讨论】:

  • 为什么不接受任何答案?

标签: php file xlsx


【解决方案1】:
<?php
require_once 'SimpleXLSX.php';

if ( $xlsx = SimpleXLSX::parse('pricelist.xlsx') ) {
  print_r( $xlsx->rows() );
} else {
  echo SimpleXLSX::parseError();
}
?>

SimpleXLSX

【讨论】:

  • 这个类比 PHPExcel 类慢得多,PHPExcel 类可以读取比这个类更多的格式。
  • SimpleXLSX 完成了这项工作,而且如此简单!这就是我所需要的 (+1)。
【解决方案2】:

PHPExcel(参见GitHub repository)可能是您的最佳选择。它非常流畅且易于使用,我对新的 XLSX 格式没有任何问题。

更新:

PHPExcel - 死亡

PHPExcel 最新版本 1.8.1 于 2015 年发布。该项目于 2017 年正式弃用,并于 2019 年永久存档。

该项目已多年未维护,不得再使用。所有用户都必须迁移到其直接继任者 PhpSpreadsheet 或其他替代方案。

【讨论】:

  • (来自匿名用户):请注意 PHPExcel 可能会占用大量内存。如果您要将它与几兆字节或更大的电子表格一起使用,则应该考虑这一点。
  • PHPExcel 在尝试加载 91kb .xlsx 文件时导致内存不足...没用的工具
  • PHPExcel 的问题不仅在于内存使用量大,还在于速度。在我的测试 XLS 文件(0.5Mb)中,PHPExcel 占用的内存是 Spreadsheet_Excel_Reader 的 5 倍(30Mb 对 6Mb),速度慢 6 倍(6 秒对 1 秒):(
  • 我还可以确认 PHPExcel 将在具有许多行和/或列的 excel 文件中使用大量资源。仅用于简单的 excel 文件。
【解决方案3】:

XLSXReader(在GitHub 上可用)基于SimpleXLSX(参见Sergey Shuchkin 的回答)。

使用XLSXReader::toUnixTimeStamp从 xlsx 转换日期。

sample.xlsx

sample.php

require (__DIR__ . '/../xlsxreader/XLSXReader.php');

// entire workbook
$xlsx = new XLSXReader('sample.xlsx');
$sheetNames = $xlsx->getSheetNames();

// loop through worksheets
foreach ($sheetNames as $sheetName) {
    $sheet = $xlsx->getSheet($sheetName);

    // worksheet header
    echo('<h3>' . htmlentities($sheetName) . '</h3><table>' . PHP_EOL);
    $xlsx_data = $sheet->getData();
    $header_row_xlsx = array_shift($xlsx_data);

    // header row
    echo('<tr>' . PHP_EOL);
    echo("\t<th>row</th>" . PHP_EOL);
    for ($i = 0; $i < count($header_row_xlsx); $i++) {
        $xlsx_field_name = '' . $header_row_xlsx[$i];
        echo("\t<th>" . htmlentities("$xlsx_field_name") . '</th>' . PHP_EOL);
    }
    echo('</tr>' . PHP_EOL);

    // loop through data rows
    $row_number = 1;
    foreach ($xlsx_data as $row_xlsx) {

        // data row
        echo('<tr>' . PHP_EOL);
        echo("\t<td>" . htmlentities("$row_number") . '</td>' . PHP_EOL);
        for ($i = 0; $i < count($row_xlsx); $i++) {
            $xlsx_field_name = '' . ($i < count($header_row_xlsx) ? $header_row_xlsx[$i] : '');
            if ("$xlsx_field_name" === "DoB") {

                // date value
                $xlsx_field_value = DateTimeImmutable::
                        createFromFormat('U', XLSXReader::toUnixTimeStamp($row_xlsx[$i]))
                        ->format('Y-m-d');
            } else {

                // non-date value
                $xlsx_field_value = $row_xlsx[$i];

            }
            echo("\t<td>" . htmlentities("$xlsx_field_value") . '</td>' . PHP_EOL);
        }
        echo('</tr>' . PHP_EOL);

        $row_number++;
    }
    echo("</table><!-- end of $sheetName -->" . PHP_EOL);
}

输出

<h3>Sheet1</h3><table>
<tr>
    <th>row</th>
    <th>Name</th>
    <th>Number</th>
    <th>DoB</th>
</tr>
<tr>
    <td>1</td>
    <td>David</td>
    <td>7</td>
    <td>1988-11-12</td>
</tr>
<tr>
    <td>2</td>
    <td>Walt</td>
    <td>8</td>
    <td>1972-01-19</td>
</tr>
</table><!-- end of Sheet1 -->

XLSXReader is a heavily modified version of:
    SimpleXLSX php class v0.4 (Artistic License)
    Created by Sergey Schuchkin from http://www.sibvision.ru - professional php developers team 2010-2011
    Downloadable from GitHub.

Key Changes include:
    Separation into two classes - one for the Workbook and one for Worksheets
    Access to sheets by name or sheet id
    Use of ZIP extension
    On-demand access of files inside zip
    On-demand access to sheet data
    No storage of XML objects or XML text
    When parsing rows, include empty rows and null cells so that data array has same number of elements for each row
    Configuration option for removing trailing empty rows
    Better handling of cells with style information but no value
    Change of class names and method names
    Removed rowsEx functionality including extraction of hyperlinks
