PHP : 列出目录和子目录中的文件到一个 XML 文件中

Question

[编辑：修复拼写错误并更新脚本]

你好，

我正在尝试列出存储在远程服务器上的文件并将该列表存储到一个 XML 文件中，该文件将在软件更新程序中使用。为此，我编写了一个递归函数，它针对每个文件调用另一个函数来写入所有必要的信息（文件名、md5 哈希和路径）。

但是，当我需要该功能转到文件树的底部时，它似乎只列出了第一组子目录。

这是我使用的代码，如果有人能告诉我我缺少什么？

我已经整理了很多代码，因为你重复了一些事情，我也减少了它，所以文档是 created/opened 在 scanRecurs 函数的第一级...

function writeXml(&$node, $pathInfo)
{
    $dom = $node->ownerDocument;
    $file = $dom->createElement("File");
    $node->appendChild($file);

//     echo "Treating ".$pathInfo['basename']." in ".$pathInfo['dirname']."<br>";
    $xmlNodeFile = $dom->createElement("Name", $pathInfo['basename']);
    $file->appendCHild($xmlNodeFile);

    $xmlPath = $dom->createElement("Path", $pathInfo['dirname'].DIRECTORY_SEPARATOR.$pathInfo['basename']);
    $file->appendChild($xmlPath);
//     echo "----Directory : ".$pathInfo['dirname']."<br>";

    $fileMd5 = md5_file($pathInfo['dirname'].DIRECTORY_SEPARATOR.$pathInfo['basename']);
    $xmlMd5 = $dom->createElement("MD5", $fileMd5);
    $file->appendChild($xmlMd5);
//     echo "----MD5 : ".$fileMd5."<br>";

    $fileSha1 = sha1_file($pathInfo['dirname'].DIRECTORY_SEPARATOR.$pathInfo['basename']);
    $xmlSha1 = $dom->createElement("SHA1", $fileSha1);
    $file->appendChild($xmlSha1);
//     echo "----SHA1 : ".$fileSha1."<br>";

} //endof writeXml function
