PHP FTP problem

[itnecor]

I usually using the codes below to connect to FTP and display its content. It work most of the server that I'm using except on the server I'm using this time. But the more unsual to is that it works when I'am using ftp_rawlist($conn_id, '/'); but not in $buff = ftp_nlist($conn_id, ".");

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

$ftp_server = '<address>';
$ftp_username = '<username>';
$ftp_password = '<password>';

$conn_id = ftp_connect("$ftp_server");
if (!$conn_id)
die ("Unable to connect to FTP server");

$login_result = ftp_login($conn_id, $ftp_username, $ftp_password);
if (!$login_result)
die ("Unable to log in to FTP server");


$buff = ftp_nlist($conn_id, ".");
//$buff = ftp_rawlist($conn_id, '/');

foreach ($buff as $value) {
$res = ftp_size($conn_id, $value);
$extension = explode('.', "$value");
echo $value;
echo "<br />\n";
}

ftp_close($conn_id);

Could it be that your directory isn't correct? Try:

$buff = ftp_nlist($conn_id, "/");

666 posts for the third time, and I was correct, the bugs do show their ugly heads after 666 posts ;)

[itnecor]

Thanks eelixduppy!

I've tried what you said but it is still not working.

[eelixduppy]

Are any errors being thrown, either to the browser or to a log file?

It doesn't make sense why this doesn't work, then...

[itnecor]

It displays nothing.

[coopster]

var_dump [php.net] the array being returned ($buff) on the ftp_nlist function. If it comes back as boolean FALSE at least you will know whether or not you are running into an error.

[itnecor]

Here is the result upon doing waht you have said.

When I'm using the $buff = ftp_nlist($conn_id, "."); the output is
bool(false) .

While $buff = ftp_nlist($conn_id, "/"); gives me an output of
array(0) { } .

I think my client has a virtual directory? Am I correct with that theory?

[coopster]

Don't know, but at least you know now that it is returning in error. Check the logs if possible, there you may find your answer.

[itnecor]

Thanks coopster for your help and time.

[coopster]

Sure, but please keep us posted, we would like to hear what you discover.

[itnecor]

The IT staff of my client told me that they do not setup any virtual directory and he told me also that I do not need to connect in PASV mode.

I tried also to increase the request timeout but nothing happened. Until now I experiencing difficulty to solve this.

[itnecor]

What I'm thinking now is to use DOS command with PHP exec(); function, because I tried using DOS to connect and it is working.

Is this correct?

exec("ftp <IP_address>");

>>> my problem with this one is how to include the logon info?

[coopster]

You could specify a text file containing your FTP commands:

ftp -s:ftpinput.txt <host>

ftpinput.txt

userid 
password

But I don't see how this is going to change anything. You are already connecting with PHP, no need to exec with DOS commands. The trouble is not in the connection, but the directory argument of the PHP function being used. If root ("/") works, but not current ("."), I would expect there should be some kind of error message being returned as the function is returning a boolean FALSE value. Still interested in what is going on, so keep us posted!

[itnecor]

Thanks again, by the way here is the reply of my client when I asked them if they have a virtual directory.

'The directory you log into is C:\FTP\Clients\project101. Your login should take you to that directory as your root. The server seems to be working well on our end. Do you use passive transfers? if so, try logging in without passive transfers, you should not have to use them. Let me know if I can be of any further assistance.'

Does this message make sense to you?

[swa66]

Their message makes little sense to me as it seems contradictory.

Connect manually to that ftp server, check the current directory as you log in. (The command to get the current directory in a ftp session is "pwd")

It'll tell you much more.

FWIW: there are many funny acting ftpd's for windows out there. In a worst case debug it using packet captures to know what's going back and forth on the wire.

[itnecor]

It says there that the currenty directory is "/". I have changed already the '.' on my program to '/' but it doesn't have an effect.
When I connect with PASV mode it give me an error of 'Warning: Invalid argument supplied for foreach() in c:\ibserver\www\auto_download\testpage.php on line 20' and when I'm connecting without a PASV mode it still displays nothing.

[swa66]

As I said there are some weird windows based ftp daemons out there.

Parsing the result of a ls (or dir, or whatever php sends to the server) isn't going to be always easy to parse into filenames.

Test the output from that server for commands like dir and ls against a well known public ftp server. If you see it differ in output, I think you'll have found the cause.

commands I'd try:
dir .
dir /
ls .
ls /

But I'd need to check what php actually sends to the servers (I didn't read the source code, sorry).

[swa66]

Did you read [bugs.php.net...]
It seems a regressing windows problem with some "me too"-s on it ...

[itnecor]

Thanks swa66! I have tried what you have said and below is the result.

[itnecor]

swa66, with regards to the bugs stated on [bugs.php.net...] I think it is not applicable to my problem, because only
$buff = ftp_nlist($conn_id, "."); is not working while $buff = ftp_rawlist($conn_id, '.'); is working.
