PHP文件搜索将目录列为文件

Question

以下脚本用于在指定路径中搜索文档/文件。它工作得很好，除了当一个子文件夹有一个子文件夹时，它将它列为一个文件/使其可点击。这不是我想要的。我希望脚本只显示每个文件夹中的文件（包括子目录中的文件）。希望我的解释不要乱七八糟，哈哈。

由于我无法发布屏幕截图，我将尝试解释。

当前文件夹结构：

vbfiles/
    -dir1/
          -subdir1/
                   -filesubdir1.doc
          -subdir2/
                   -filesubdir2.doc
          -dir1file1.doc
          -dir1file2.doc
          -dir1file3.doc
    -dir2/
          -subdir3/
                   -filesubdir3.doc
          -subdir4/
                   -filesubdir4.doc
          -dir2file4.doc
          -dir2file5.doc
          -dir2file6.doc

结果（我要删除的标记为“

Found 14 file(s)

dir1
 dir1file3.doc
 dir1file2.doc
 subdir1 <-- NO
 subdir2 <-- NO
 dir1file1.doc
subdir1
 filesubdir1.doc
subdir2
 filesubdir2.doc
dir2
 subdir3 <-- NO
 dir2file4.doc
 dir2file5.doc
 subdir4 <-- NO
 dir2file6.doc
subdir3
 filesubdir3.doc
subdir4
 filesubdir4.doc

此函数列出目录中的文件。它也接近嵌套的子目录。当我需要相同的功能时，我写了这个。

/**
 * Return files of desired extension from a directory
 *
 * @author Pankaj Garg <garg.pankaj15@gmail.com>
 *
 * @param string $_dirPath   path to directory
 * @param string $_extension desired file extension
 * @param int    $_before    files to get before this time (in seconds)
 * @param int    $_limit     no of files
 *
 * @return array $_scannedFiles  array of files
 */
function ScanFilesFromDirectory($_dirPath, $_extension, $_before = 0, $_limit = 10)
{
    $_scannedFiles = array();

    if (empty($_extension)) {
        return $_scannedFiles;
    }
    if (!is_dir($_dirPath)) {
        return $_scannedFiles;
    }

    //If extension starting with '.', then remove it
$_extension = (stripos($_extension, '.') === 0) ? substr($_extension, 1) : $_extension;
$_handler   = opendir($_dirPath);

while ($_fileName = readdir($_handler)) {
    //for files starting with '.'
    if (stripos($_fileName, '.') === 0) {
        continue;
    }

    if (is_dir($_dirPath . DIRECTORY_SEPARATOR . $_fileName)) {
        $_scannedFiles = array_merge($_scannedFiles, ScanFilesFromDirectory($_dirPath . DIRECTORY_SEPARATOR . $_fileName, $_extension, $_before, $_limit));
    } else if (is_file($_dirPath . DIRECTORY_SEPARATOR . $_fileName)) {
        if (preg_match('/' . preg_quote($_extension) . '$/', $_fileName)) {
            if (($_before != 0 && time() - filemtime($_dirPath . DIRECTORY_SEPARATOR . $_fileName)) < $_before) {
                continue;
            }
            $_scannedFiles[] = substr($_fileName, 0, -strlen($_extension) - 1);
        }
    }
    if (count($_scannedFiles) >= $_limit) {
        break;
    }
}
closedir($_handler);

return $_scannedFiles;
}
