php sftp文件或文件夹

Question

i am attempting to create a web based sftp page, the only part i am having problems with is trying to determin the the listed file is a file or folder. i am sucessfully listing a directory using

$connection = ssh2_connect($_SESSION['Server'], $_SESSION['Port']);
if(ssh2_auth_password($connection, $_SESSION['Username'], $_SESSION['Password']))
{
    $sftp = ssh2_sftp($connection);
    $dir = "ssh2.sftp://$sftp/$directory";
    $handle = opendir($dir);
    while (false !== ($file = readdir($handle))) 
    {
        if ($file != "." && $file != "..")
        {
            $temp=$file;
            if(strlen($directory) > 0)
                $Path=$directory."/".$file;
            else
                $Path=$file;

            $statinfo = ssh2_sftp_stat($sftp, "/".$Path);
            echo "<a href=\"list.php?dir=".urlencode($Path)."\">$temp</a><br />";
        }
    }
     closedir($handle);
}

i attempted to use the is_dir() and is_file() php function on $file which works sucessfully when working on local filesystem, but when using SFTP both come back FALSE, i attempted to use ssh2_sftp_stat() but this only gives uid, gid, size access and modified times and i dont think there is anyting that can be used to identify files of folders, if anyone has a way to resolve this i would appreaciate it greatly

I would strongly suggest using phpseclib for SSH2 purposes. It greatly simplifies tasks like this.

Solution for your problem using phpseclib should go something like this:

include('Net/SFTP.php');

$sftp = new Net_SFTP($_SESSION['Server'] . ':' . $_SESSION['Port']);
if (!$sftp->login($_SESSION['Username'], $_SESSION['Password'])) {
    exit('Login Failed');
}

foreach($sftp->rawlist($dir) as $filename => $attrs) {
    if ($attr['type'] == NET_SFTP_TYPE_REGULAR) {
        echo $filename . ' is a regular file!';
    }
    if ($attr['type'] == NET_SFTP_TYPE_DIRECTORY) {
        echo $filename . ' is a directory!';
    }
}

These are the file type constants phpseclib uses:

file_types = array(
    1 => 'NET_SFTP_TYPE_REGULAR',
    2 => 'NET_SFTP_TYPE_DIRECTORY',
    3 => 'NET_SFTP_TYPE_SYMLINK',
    4 => 'NET_SFTP_TYPE_SPECIAL'
);
