从FTP返回文件树

Question

我试图从FTP服务器列出文件.我希望将一个子目录和文件数组作为树来获取,如下所示:

folder1
       file1.txt
       file2.txt
folder2
       folder2a
               file1.txt
               file2.txt
               file.3txt
       folder2b
              file1.txt

现在我的数组将是类似的

[folder1]=>array(file1.txt,file2.txt) 
[folder2]=>array([folder2a]=>array(file1.txt,file2txt,file3.txt)
[folder2b]=>array(file1.txt))

注意:上面的数组可能不是确切的语法,只是为了让我知道我在寻找什么.我试过ftp_nlist()但似乎只返回文件和文件夹,但不返回子文件夹中的文件.以下是我的代码如何显示的示例

 // set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// get contents of the ftp directory
$contents = ftp_nlist($conn_id, ".");

// output $contents
var_dump($contents);

以上只有文件夹列表而不是文件列表.任何人都知道如何解决这个问题？谢谢.

ftp_nlist()不会递归地获取文件和目录,它只返回指定路径上的所有文件和文件夹.您可以编写一个函数来以递归方式获取结果.这是一个有人编写的递归函数示例,我在PHP ftp_nlist()文档中找到了它:

<?php 
/** 
 * ftpRecursiveFileListing 
 * 
 * Get a recursive listing of all files in all subfolders given an ftp handle and path 
 * 
 * @param resource $ftpConnection  the ftp connection handle 
 * @param string $path  the folder/directory path 
 * @return array $allFiles the list of files in the format: directory => $filename 
 * @author Niklas Berglund 
 * @author Vijay Mahrra 
 */ 
function ftpRecursiveFileListing($ftpConnection, $path) { 
    static $allFiles = array(); 
    $contents = ftp_nlist($ftpConnection, $path); 

    foreach($contents as $currentFile) { 
        // assuming its a folder if there's no dot in the name 
        if (strpos($currentFile, '.') === false) { 
            ftpRecursiveFileListing($ftpConnection, $currentFile); 
        } 
        $allFiles[$path][] = substr($currentFile, strlen($path) + 1); 
    } 
    return $allFiles; 
} 
?>
