如何使用php更新docx文件的自定义属性

$docxFile = 'path/to/your/docx/file.docx';
$zip = new ZipArchive;
if ($zip->open($docxFile) === true) {
    $tempDir = 'path/to/temp/directory';
    $zip->extractTo($tempDir);
    $zip->close();
}

$coreFile = $tempDir . '/docProps/core.xml';
$xml = simplexml_load_file($coreFile);
$customProperties = $xml->children('http://schemas.openxmlformats.org/package/2006/metadata/core-properties');
$customProperties->yourCustomProperty = 'yourNewValue';

$xml->asXML($coreFile);

$newDocxFile = 'path/to/your/new/docx/file.docx';
$zip = new ZipArchive;
if ($zip->open($newDocxFile, ZipArchive::CREATE) === true) {
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($tempDir));
    foreach ($files as $name => $file) {
        if (!$file->isDir()) {
            $filePath = $file->getRealPath();
            $relativePath = substr($filePath, strlen($tempDir) + 1);
            $zip->addFile($filePath, $relativePath);
        }
    }
    $zip->close();
}

function deleteDirectory($dir) {
    if (!file_exists($dir)) {
        return true;
    }
    if (!is_dir($dir)) {
        return unlink($dir);
    }
    foreach (scandir($dir) as $item) {
        if ($item == '.' || $item == '..') {
            continue;
        }
        if (!deleteDirectory($dir . DIRECTORY_SEPARATOR . $item)) {
            return false;
        }
    }
    return rmdir($dir);
}

deleteDirectory($tempDir);
