Here is a FTP-abstraction-class which supports the most commands.
Also it works on TLS, SSLv2 etc. by using stream_crypto_enable()

Many thanks to WEZ at this point after all the years :-)

Here is the way you can do it:
First of all, copy paste the code in your php file.

Then run your script on the Server where you want to execute your code:

Fill in the Forms: 
1) Server Path or IP like abc.com/1.2.3.4 only.
2) FTP Username
3) FTP Password
4) FTP Path, where you want to put the file, check the Folder permission first.

This took me a few hours to work out. It is based on the code below I've just added a string replace to convert pathname given by Windows to Unix pathname. Hope it saves somebody some time. Enjoy! (Also, delete file function is included:))

I had some major problems running ftp_connect from my Web Browser and not from the CLI from 1 server and yet from another Internal server I had no trouble at all. After a few hours I figured out this was because SELINUX was enabled on one server and DISABLED on the server that it worked on.
So in short, if you are having trouble with connecting in your Web Browser make sure you have HTTPD connect's enabled in it like so at the command prompt:
; Turns it on temporarily.
/usr/sbin/setsebool httpd_can_network_connect=1
; Turns it on Permenantly
/usr/sbin/setsebool -P httpd_can_network_connect=1
I hope this helps make someones life a little easier. :)
(I actually found this fix on the fopen manual page).

A function to get a remote file and return it's contents, instead of saving to a local file, was missing - here it is:
function ftp_fetch($ftp_stream, $remote_file) {
ob_end_flush();
ob_start();
$out = fopen('php://output', 'w');
if (!ftp_fget($ftp_stream, $out, $remote_file, FTP_ASCII)) die('Unable to get file: ' . $remote_file);
fclose($out);
$data = ob_get_clean();
return $data;
}
It works the same as ftp_get(), but instead returns the contents of the remote file - for example:
$ftp = ftp_connect('my.server.com', 21, 60);
ftp_login($ftp, 'username', 'password');
$data = ftp_fetch($ftp, 'path/to/remote.file');
echo $data;
Note, I use it to fetch text-files from a server - if you need to fetch binary files, change FTP_ASCII to FTP_BINARY .. but most likely, getting files to memory is only useful for smaller files, e.g. plain text, xml, etc.

I fixed the below upload script to work with Windows uploads (and updated some of the syntax). I also added a Javascript "progress indicator" for those of us who don't use PHP 5.2

Here is an example for downloading a remote ftp structure to local server, useful for migrating sites from one server to another, especially when you are upgrading ensim ;)

It may seem obvious to others, but it had me stumped for nearly an hour! If you can connect to an ftp site but some functions (list, put, get etc) don't work, then try using ftp_pasv and set passive mode on.

<?php

// setup $host and $file variables for your setup before here...

$hostip gethostbyname($host);
$conn_id ftp_connect($hostip);

// login with username and password
$login_result ftp_login($conn_id$ftp_user_name$ftp_user_pass);

// IMPORTANT!!! turn passive mode on
ftp_pasv $conn_idtrue );

if ((!
$conn_id) || (!$login_result)) {
  echo 
"FTP connection has failed!";
  echo 
"Attempted to connect to $host for user $ftp_user_name";
  die;
} else {
  echo 
"Connected to $host, for user $ftp_user_name<br>";
  echo 
"Host IP is $hostip<br>";
  
  
// upload a file
  
if (ftp_put($conn_id$remote_file$fileFTP_ASCII)) {
    echo 
"successfully uploaded $file<br>";
  } else {
    echo 
"There was a problem while uploading $file<br>";
  }
    
  
// close the connection
  
ftp_close($conn_id);
}
?>

If you prefer a OO-approach to the FTP-functions, you can use this snippet of code (PHP5 only! and does add some overhead). It's just a "start-up", extend/improve as you wish...
You can pass all ftp_* functions to your object and stripping ftp_ of the function name. Plus, you don't have to pass the ftp-resource as the first argument.

For example:
<?php
ftp_delete
($ftp$file);    // Where $ftp is your ftp-resource
?>

Can become:
<?php
$ftp
->delete($file);        // Where $ftp is your FTP-object
?>

Code:
<?php

class FTP {

    private 
$ftp;
    
    
/* public Void __construct(): Constructor */
    
public function __construct($host$port 21$timeout 90) {
        
$this->ftp ftp_connect($host$port$timeout);
    }
    
    
/* public Void __destruct(): Destructor */
    
public function __destruct() {
        @
ftp_close($this->ftp);
    }

    
/* public Mixed __call(): Re-route all function calls to the PHP-functions */
    
public function __call($function$arguments) {
        
// Prepend the ftp resource to the arguments array
        
array_unshift($arguments$this->ftp);
        
        
// Call the PHP function
        
return call_user_func_array('ftp_' $function$arguments);

Here's a little function that I created to recurse through a local directory and upload the entire contents to a remote FTP server.

In the example, I'm trying to copy the entire "iwm" directory located at /home/kristy/scripts/iwm to a remote server's /public_html/test/ via FTP.

The only trouble is that for the line "if (!ftp_chdir($ftpc,$ftproot.$srcrela))", which I use to check if the directory already exists on the remote server, spits out a warning about being unable to change to that directory if it doesn't exist.

But an error handler should take care of it.

My thanks to the person who posted the snippet on retrieving the list of files in a directory.

For the version of the script that echo's it's progress as it recurses & uploads, go to: http://pastebin.com/73784

I have written an OpenSource ZIP2FTP interface, which actually takes a given ZIP file and decompresses it in the folder on an FTP server you specify...
Therefore it may be quite interesting for you people interested in FTP, its adress is http://zip2ftp.alishomepage.com ; those who directly want the source may visit http://zip2ftp.alishomepage.com/?do=getSource

Here's another FTP interface over PHP (also uses MySQL)
http://myftp.alishomepage.com
PS: this script will ALSO allow you to download its source... So it becomes interesting for YOU PROGRAMMERS as well :D

I think what some other posts were trying to say which may need clarification is that in PHP 4.2.3, ftp_connect("myhost.com") was failing most of the time, except it would work like every few minutes.
The fix is that ftp_connect seems to have a bug resolving addresses. If you do:
$hostip = gethostbyname($host);
$conn_id = ftp_connect($hostip);
It seems to solve the problem.
(Other users referred to an ftpbuf() error... not sure what that is, but this should fix it.)

connection to a ftp server across proxy
$ftp_server = "proxy"; f.e. 123.456.789.10
$ftp_user_name = "username@ftpserver"; f.e. exampleuk@www.example.uk
$ftp_user_pass = "password";
$conn_id = ftp_connect($ftp_server, 2121);
$login_result = ftp_login( $conn_id, $ftp_user_name, $ftp_user_pass );
