FTP Script

dcjones

hi all,

I am having an issue with a small FTP script I am putting together.

When I run the script I get the following error:

Warning: ftp_login() expects parameter 1 to be resource, boolean given in /home/vhosts/example.com/httpdocs/xml/planeh.php on line 7
FTP connection has failed!Attempted to connect to ftp.example.com for user myusername

Line 7 starts with: $login_result

My script looks like:

$ftp_server    = 'localhost'; 
$ftp_user_name    = 'username'; 
$ftp_user_pass    = 'password'; 

$conn_id = ftp_connect($ftp_server);  

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);  

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_server, for user $ftp_user_name connection ID is $conn_id<br/><br/>"; 
       } 

ftp_close($conn_id);

Can anyone see what is wrong.

No, I can't. Let's debug it:

$ftp_server    = 'localhost';
$ftp_user_name    = 'username';
$ftp_user_pass    = 'password';

$conn_id = ftp_connect($ftp_server);

// What in the world is wrong? DEBUGging line...  

var_dump($conn_id);exit;

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);  

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_server, for user $ftp_user_name connection ID is $conn_id<br/><br/>";
       }

ftp_close($conn_id);

Incidentally, your domain name might be in your error message up there. You may wish to edit your post and make that read "mysite.com" or something.

Hi dalecosp,

The result of the var_dump is:

bool(false)

I have also spoken to my hosting company and they say they have no restrictions on thier firewall that would prevent this script from working.

If I jump into DOS on my PC I can FTP with no issues.

If I set up one of my FTP clients under MS Windows, again no issues.

It just when I run it as a PHP script.

Any ideas.

As the PHP manual states for the return value of [man]ftp_connect/man:

PHP Manual wrote:
Returns a FTP stream on success or FALSE on error.

So, since you're getting FALSE (you should be testing each step of the process to catch these types of errors), then that's your problem.

Whether the problem is that the machine is firewalled or otherwise blocked from connecting to the remote FTP server OR the address for the remote server you're specify is incorrect, it's hard to say.

Do you have error_reporting set to E_ALL?

You might also make sure you didn't fat-finger your passphrase.

Works fine here with PHP and an anonymous login:

Connected to foo.foobarbaz.com, for user anonymous connection ID is Resource id #4<br/><br/>

And you've still got your domain up there, the name of a service, and a <valid?> username. Brad, you might want to do a little intervention there....

When I first read the post, I didn't really see much need to edit that stuff out. However, that was before this:

@: You'll want to look into network/firewall errors on the webserver where you're running this PHP script as well as changing your FTP password (hint: I was able to login successfully on the first attempt).
