Send file FTP over SSL with custom port number

Question

I have asked the question before but in a different manner. I am trying taking form data, compiling into a temporary CSV file and trying to send over to a client via FTP over SSL (this is the only route I am interested in hearing solutions for unless there is a workaround to doing this, I cannot make changes). I have tried the following:

1. ftp_connect - nothing happens, the page just times out
2. ftp_ssl_connect - nothing happens, the page just times out
3. curl library - same thing, given URL it also gives error.

I am given the following information:

• FTPS Server IP Address
• TCP Port (1234)
• Username
• Password
• Data Directory to dump file
• FTP Mode: Passive

very, very basic code (which I believe should initiate a connection at minimum): Code:

<?php
$ftp_server = "00.000.00.000";  //masked for security
$ftp_port = "1234"; // masked but not 990
$ftp_user_name = "username";
$ftp_user_pass = "password";


// set up basic ssl connection
$conn_id = ftp_ssl_connect($ftp_server, $ftp_port, "20");

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
ftp_pasv($conn_id, true);

echo ftp_pwd($conn_id); // /
echo "hello";

// close the ssl connection
ftp_close($conn_id);

?>

When I run this over a SmartFTP client, everything works just fine. I just can't get it to work using PHP (which is a necessity). Has anybody had success doing this in the past? I would be very interested to hear your approach.

EDIT I added the ftp_pasv() command after ftp_login as mentioned below but am still unable to connect. I am given the following errors:

Warning: ftp_login() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\test.php on line 12

Warning: ftp_pasv() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\test.php on line 14

Warning: ftp_pwd() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\test.php on line 16

Warning: ftp_close() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\test.php on line 20

Answer 1

Is FTP enabled in your PHP installation? Use phpinfo(); to echo your installation info. There should be a section for ftp, with "FTP Support - enabled" in a table.

Answer 2

First, you need to find out which secure FTP you are using,

1. SFTP : SSH FTP
2. FTPS : FTP over SSL

For FTPS to work, the openssl module must be statically linked (not installed as a dynamic extension).

SFTP requires PECL ssh2 extension.
