使用 PHP Word 阅读 MS Word 文档

Question

我已经在 PHPStorm (IDE) 上安装并设置了 PHP Word。我正在尝试使用 PHPWord 从下面标题为 'helloWorld.docx' 的 word 文档中读取“从昨天学习，为今天而活，为明天的希望......”。

这是我目前加载和阅读文档的代码：

<?php

require_once 'PHPWord/bootstrap.php';

$objReader = \PhpOffice\PhpWord\IOFactory::createReader("Word2007");
$phpWord = $objReader->load("helloWorld.docx");

$sections = $phpWord->getSection(0);

echo var_dump($sections);

输出：

完整的输出太长，无法发布，但如果向下滚动，您可以在此 sn-p 中看到我要查找的字符串

我的主要问题是“有没有办法在不使用 var_dump 和搜索大量输出的情况下找到这个字符串？”

Answer 1

这是从 docx 文件中检索文本内容的示例代码。

$content = '';

require_once dirname(__FILE__) . '/includes/phpoffice/vendor/autoload.php';
$phpWord = \PhpOffice\PhpWord\IOFactory::load('helloworld.docx');

foreach($phpWord->getSections() as $section) {
    foreach($section->getElements() as $element) {
        if (method_exists($element, 'getElements')) {
            foreach($element->getElements() as $childElement) {
                if (method_exists($childElement, 'getText')) {
                    $content .= $childElement->getText() . ' ';
                }
                else if (method_exists($childElement, 'getContent')) {
                    $content .= $childElement->getContent() . ' ';
                }
            }
        }
        else if (method_exists($element, 'getText')) {
            $content .= $element->getText() . ' ';
        }
    }
}

echo $content;

Answer 2

文本信息位于[text] 属性中，而这些属性又嵌套在[elements] 属性中。只需使用浏览器的“在文本中查找内容”功能在您在浏览器中获取的对象中搜索它们，即可查看您正在搜索的文本。

这两个属性受到保护，因此您必须将它们设为公开，才能访问/提取它们。

这些属性在 PHPWord 库中的定义位置：https://stackoverflow.com/a/50989007/8510094

一旦你将它们设为public，你就可以开始切断你收到的对象的每一层，从而访问[elements]->[text]属性只是“树”下一层的对象。

所以，算法是 1) 找到这些[text] 属性，2) 查看保存这些属性的对象的路径，3) 逐级切断更高级别的对象和数组，4) 得到一个对象，其中[elements]->[text] 属性只是第二级，5) 将 [text] 属性的所有值收集到一个数组中。

不要尝试使用foreach 循环、递归函数等尝试访问文本。由此产生的物体是巨大的。您将不会获得这么大的内存或时间来迭代、展平、减少等如此大的多维关联数据数组。

或者，您可以对 PHPWord 库文件进行某些更改，并且不会在您将 Word 文件加载到 PHPWord 时获得的结果对象中获得不必要的属性和值（样式、段落信息等）。

在 PHPSpreadsheet 中，他们实现了一种仅从 Excel 文件中获取实际数据的方法（去除格式、样式信息等）。另一方面，PHPWord 也声明了$readDataOnly 属性，但它们就停在那里了，并且由于某种原因没有实现仅读取实际文本数据的机制。
