PHP FTP functions slow?

[PaulM]

I'm trying to clone an FTP folder using PHP. I haven't used PHP for quite a while so I might be doing something wrong.

Just listing an FTP folder with ~900 files in about 20 directories takes 2-3 minutes . Can anyone see a problem or are the ftp_* functions in PHP just really slow:

<?php
set_time_limit(0);

// FTP details omitted :p

function ftp_recursive_list($resource, $dir)
{
    $files = ftp_nlist($resource, $dir);
    foreach ($files as $file)
    {
        if ($file == '.' || $file == '..') continue;

        $fullPath = $file;
        if (!empty($dir) && !in_array($dir, array('.', '/')))
        {
            $fullPath = $dir . '/' . $fullPath;
        }
        $fileSize = ftp_size($resource, $fullPath);

        // Just outputting file/size instead of copying while testing
        printf("%s (%d)<br />", $fullPath, $fileSize);

        if ($fileSize == -1) ftp_recursive_list($resource, $fullPath);
    }
}

$handle = ftp_connect($host, $port);
if ($handle)
{
    if (!ftp_login($handle, $user, $pass))
    {
        ftp_close($handle);
        die("Invalid Login");
    }
    // Tried with and without passive
    ftp_pasv($handle, true);

    ftp_recursive_list($handle, $dir);
    ftp_close($handle);
}

?>

FTP clients can list all the files almost instantly, and wget can clone the entire FTP folder in around 30 seconds.

Thanks in advance for any help.

I'll test you code on my server later and let you know how long it takes.
