PHP 讀取 xlsx Excel 2007 文件

Question

我正在使用 oleread 讀取上傳的 xls 文件。 但我無法讀取以 excel-2007 格式保存的 xlsx 文件。 有人可以幫助我了解如何在 PHP 中讀取 xlsx 文件。

Answer 1

<?php
require_once 'SimpleXLSX.php';

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

簡單的XLSX

Answer 2

PHPExcel （請參閱GitHub 存儲庫）可能是您的最佳選擇。 它非常流暢且易於使用，我對新的 XLSX 格式沒有任何問題。

PHPExcel - 死了

PHPExcel 最新版本 1.8.1 於 2015 年發布。該項目於 2017 年正式棄用，並於 2019 年永久存檔。

該項目已多年未維護，不得再使用。 所有用戶都必須遷移到其直接繼承者PhpSpreadsheet或其他替代方案。

Answer 3

XLSXReader （可在GitHub 上獲得）基於SimpleXLSX （請參閱 Sergey Shuchkin 的回答）。

使用XLSXReader::toUnixTimeStamp從 xlsx 轉換日期。

示例.xlsx

示例.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);
}

輸出

<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

雖然我建議從GitHub獲取最新代碼，但整個 1-file 庫不到 400 行代碼，因此我在上面包含了當前版本 (11/10/2018)。
