要操作Word文檔內容，可以使用PHPWord庫來實現。以下是使用PHPWord庫來獲取和操作Word文檔內容的步驟：

1. 安裝PHPWord庫

首先，需要安裝PHPWord庫。可以通過Composer來安裝PHPWord庫：

composer require phpoffice/phpword

2. 創建一個新的Word文檔

require_once 'vendor/autoload.php';

$phpWord = new \PhpOffice\PhpWord\PhpWord();
$section = $phpWord->addSection();

$section->addText('Hello World!');
$section->addText('This is a new Word document.');

$phpWord->save('hello_world.docx');

3. 讀取Word文檔內容

require_once 'vendor/autoload.php';

$phpWord = \PhpOffice\PhpWord\IOFactory::load('hello_world.docx');

foreach ($phpWord->getSections() as $section) {
    foreach ($section->getElements() as $element) {
        if ($element instanceof \PhpOffice\PhpWord\Element\Text) {
            echo $element->getText() . PHP_EOL;
        }
    }
}

4. 修改Word文檔內容

require_once 'vendor/autoload.php';

$phpWord = \PhpOffice\PhpWord\IOFactory::load('hello_world.docx');

foreach ($phpWord->getSections() as $section) {
    foreach ($section->getElements() as $element) {
        if ($element instanceof \PhpOffice\PhpWord\Element\Text) {
            $element->setText('New text');
        }
    }
}

$phpWord->save('hello_world_modified.docx');

通過以上步驟，你可以使用PHPWord庫來獲取和操作Word文檔內容。
