I didn't quite like my FTP program since I had to make all the settings all over when i restarted the client, so I made this script for simple ftp uploading, its running as a CLI app.

<?php

    //if STDIN isn't defined, define it
    if (!defined("STDIN"))
    {
    
        define("STDIN", fopen("php://stdin", "r"));
        
    }
    
    echo "FTP file uploader\r\n\r\n";

    echo "Server: ";

    //trim() all the fgets cause it seams to add a \n
    $server = trim(fgets(STDIN));
    
    echo "Username: ";
    
    $username = trim(fgets(STDIN));
    
    echo "Password: ";
    
    $password = trim(fgets(STDIN));
    
    $connect = ftp_connect($server);
    $login = ftp_login($connect, $username, $password);
    
    if ((!$connect) || (!$login))
    {
    
        exit("Login failed.\r\n");
        
    }
    
    echo "Connected\r\n";

    echo "PASV (Y/Any key = Off): ";
    
    if(trim(fgets(STDIN)) == "Y")
    {

        //enable passive mode
        ftp_pasv($connect, true);
    
            echo "PASV: On\r\n";
        
    }
    else
    {
    
        echo "PASV: Off\r\n";

    }

    $showContent = ftp_nlist($connect, "");
    
    echo "Listing Contents:\r\n";
        
        var_dump($showContent);

    echo "File to upload: ";
    
    $file = trim(fgets(STDIN));
    
    //escape the uploading process by typing "exit;"
    if ($file == "exit;")
    {
    
        exit;
    
    }
    
    //use "$file, $file" since the file shouldn't be renamed, also if its a binary file change the last argument to FTP_BINARY
    $upload = ftp_put($connect, $file, $file, FTP_ASCII);
    
    if (!$upload)
    {
    
        exit("Upload failed.\r\n");
        
    }
    else
    {
    
        echo "The file \"" . $file . "\" was successfully uploaded. :)\r\nSize of \"" . $file . "\": " . filesize($file) / 1024 ."kb.\r\n";
        echo "My work is done, bye.\r\n";
        
    }
    
    ftp_close($connect);

After looking everywhere for a "FULLY WORKING" ftp uploader script, I finally came up with this, by using a lot of various one’s I found on the web. If you find a better way of doing something, please let me know. Thanks, and Enjoy

<?php
  if(isset($_POST['SubmitFile'])){
      $myFile = $_FILES['txt_file']; // This will make an array out of the file information that was stored.
      $file = $myFile['tmp_name'];  //Converts the array into a new string containing the path name on the server where your file is.
 
      $myFileName = basename($_POST['txt_fileName']); //Retrieve filename out of file path

      $destination_file = "/".$myFileName;  //where you want to throw the file on the webserver (relative to your login dir)

      // connection settings
      $ftp_server = "127.0.0.1";  //address of ftp server.

      $conn_id = ftp_connect($ftp_server);        // set up basic connection
      $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass) or die("<h2>You do not have access to this ftp server!</h2>");   // login with username and password, or give invalid user message

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:))

<?php    
$myFile = $_FILES['file']; // This will make an array out of the file information that was stored.
    $file = $myFile['tmp_name'];  //Converts the array into a new string containing the path name on the server where your file is.
    $myFileName = $_POST['MyFile']; //Retrieve file path and file name    
    $myfile_replace = str_replace('\\', '/', $myFileName);    //convert path for use with unix
    $myfile = basename($myfile_replace);    //extract file name from path
    $destination_file = "/".$myfile;  //where you want to throw the file on the webserver (relative to your login dir)
    // connection settings
    $ftp_server = "127.0.0.1";  //address of ftp server (leave out ftp://)
    $ftp_user_name = ""; // Username
    $ftp_user_pass = "";   // Password
    $conn_id = ftp_connect($ftp_server);        // set up basic connection
    // login with username and password, or give invalid user message
    $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass) or die("<h1>You do not have access to this ftp server!</h1>");
    $upload = ftp_put($conn_id, $destination_file, $file, FTP_BINARY);  // upload the file
    if (!$upload) {  // check upload status
        echo "<h2>FTP upload of $myFileName has failed!</h2> <br />";

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.

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_id, true );

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, $file, FTP_ASCII)) {
    echo "successfully uploaded $file<br>";
  } else {
    echo "There was a problem while uploading $file<br>";
  }
    
  // close the connection
  ftp_close($conn_id);
}
?>

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

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.)

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

    // connect to the destination FTP & enter appropriate directories both locally and remotely
    $ftpc = ftp_connect("ftp.mydomain.com");
    $ftpr = ftp_login($ftpc,"username","password");

Also it works on TLS, SSLv2 etc. by using stream_crypto_enable()

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);
    }
    
}

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

<?php
if(isset($_POST['start_upload']) && $_FILES['txt_file']['name'] != ""){
     
    $local_file = $_FILES['txt_file']['tmp_name']; // Defines Name of Local File to be Uploaded

    $destination_file = "/".basename($_FILES['txt_file']['name']);  // Path for File Upload (relative to your login dir)

    // Global Connection Settings
    $ftp_server = "127.0.0.1";      // FTP Server Address (exlucde ftp://)
    $ftp_user_name = "username";     // FTP Server Username
    $ftp_user_pass = "password";      // Password

    // Connect to FTP Server
    $conn_id = ftp_connect($ftp_server);
    // Login to FTP Server
    $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
    
    // Verify Log In Status
    if ((!$conn_id) || (!$login_result)) {
        echo "FTP connection has failed! <br />";

This is a simple script writen by me which allows the user
run it in console and get tree from FTP Server.

<?php
$argv = $_SERVER["argv"];
$argv = array_slice($argv,1);
if (getenv("HTTP_HOST")) {exit("For bash execution only!");}
if ((empty($argv[0])) || (empty($argv[1]))) {exit("Usage: thisscript.php 10.0.0.10 /games/Arcade/
where 10.0.0.10 is the FTP Server and /games/Arcade is the start path on FTP\n");}

// connect to the ftp server
$connect_id = ftp_connect($argv[0]);
// login on the server
if ($connect_id) { $login_result = ftp_login($connect_id, 'anonymous', 'JustForFun'); }
// check connection
if ((!$connect_id) || (!$login_result)) {
   echo "Unable to connect the remote FTP Server!\n";
   exit;
}
function ftp_get_dir ($ftp_dir) {
global $connect_id;
$ftp_contents = ftp_nlist ($connect_id, $ftp_dir);
    for ($myCounter_for_server_elements = 0; !empty ($ftp_contents[$myCounter_for_server_elements]);
$myCounter_for_server_elements++)
    {
// get elements list in current dir
        echo $argv[0] . $ftp_dir . $ftp_contents[$myCounter_for_server_elements] . "\n";
        ftp_get_dir ($ftp_dir . $ftp_contents[$myCounter_for_server_elements] . '/');
    }
}
ftp_get_dir ($argv[1]);
// close connection
ftp_close($connect_id);
?>
