Problems with FTP on linux

Hi guys!

I use CI as command string. The code is:

Code:
function run_ftp()
    {
        $config['hostname'] = 'ftp.something';
        $config['username'] = 'username';
        $config['password'] = 'password';
        $config['port']     = '21';
        $config['passive']  = FALSE;
        $config['debug']    = TRUE;
        
        $this->load->library('ftp');

        $this->ftp->connect($config);
        
        $list = $this->ftp->list_files('/data/folder/');

        $i = 1;
        $file_need = '';
        
        foreach($list as $file)
        {
            if(substr($file, -3) == '.gz')
            {
                $file_date = substr($file, -9, 6);

                if($file_date > $this->file_date_sample)
                {
                    $file_need = $file;
                }
            }
            
            $i += 1;
        }
        echo $file_need;
                
        $this->ftp->close();
            
    }

So, this code works perfectly on Windows machine. But if I run it on Linux box it returns the error message:

Quote:<p>Severity: Warning</p>
<p>Message: Invalid argument supplied for foreach()</p>
<p>Filename: controllers/balin_ftp.php</p>
<p>Line Number: 31</p>

Line 31 is "foreach($list as $file)"

I assume that $list is not an array. But why?
Any help is appreciated.

Maranax,
Keep in mind Linux is case sensitive. So if your folder is /Data instead of /data your script will fail. I am unsure of this but I believe by quickly looking at your script that if the FTP directory contains no files or directories your script may fail out.

ranjudsokomora,

thank you for your reply.
Good point.
I've checked my code again for case sensitivity... Well, everything looks fine. The directories on ftp server are lower cased.
I ran the script again and I got some more information. The full error message was:

Quote:<p>Severity: Warning</p>
<p>Message: ftp_nlist(): php_connect_nonb() failed: Operation now in progress (115)</p>
<p>Filename: libraries/Ftp.php</p>
<p>Line Number: 465</p>

</div><div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Warning</p>
<p>Message: Invalid argument supplied for foreach()</p>
<p>Filename: controllers/balin_ftp.php</p>
<p>Line Number: 31</p>

Maranax,
Try this:
Code:
$config['hostname'] = 'ftp.something';
$config['username'] = 'username';
$config['password'] = 'password';
$config['port']     = '21';
$config['passive']  = FALSE;
$config['debug']    = TRUE;
        
$this->load->library('ftp');

$this->ftp->connect($config);
        
$list = $this->ftp->list_files('/data/folder/');
echo "<pre>";
print_r($list);
echo "</pre><br /><br />";
EXIT;

What result are you given?

#5
[eluser]Maranax[/eluser]
Here we go:


<pre></pre><br /><br />


Means - nothing.

Maranax,
Are there any files or directories in your ftp path? You may also want to turn passive on if you are still having problems.

#7
[eluser]Maranax[/eluser]
Yes, there are around 10-15 files.
I tried to change config['passive'], but it's still the same...

#8
[eluser]Maranax[/eluser]
Ok, seems like it doesn't like the path...

I rewrote the code:

Code:
$conn_id = ftp_connect('ftp.smth');

        // login with username and password
        $login_result = ftp_login($conn_id, 'user', 'password');

        // check connection
        if ((!$conn_id) || (!$login_result)) {
            echo "FTP connection has failed!";
            echo "Attempted to connect to $ftp_server for user $ftp_user_name";

            exit;
        } else {
            echo "Connected to ftp, for user user";
            return ftp_nlist($conn_id, "/");    

        }

        ftp_close($conn_id);

So, it connects, but returns nothing.
I'll be investigating... Maybe there is something wrong with php installation.
