Введение

Функции этого модуля обеспечивают доступ к серверам по протоколу FTP (File Transfer Protocol), определенному в http://www.faqs.org/rfcs/rfc959. Модуль позволяет выполнять множество довольно сложных операций. Если требуется лишь прочитать или записать файл на сервере FTP, можно воспользоваться ftp:// ссылками и функциями для работы с файловой системой, которые более просты в использовании.

Требования

Эти функции всегда доступны.

Установка

Для использования FTP функций, вы должны указать директиву --enable-ftp во время установки PHP 4 или --with-ftp при использовании PHP 3.

Версия PHP для Windows имеет встроенную поддержку данного расширения. Это означает, что для использования данных функций не требуется загрузка никаких дополнительных расширений.

Настройка во время выполнения

Данное расширение не определяет никакие директивы конфигурации в php.ini.

Типы ресурсов

Этот модуль использует один тип ресурса - идентификатор соединения с FTP сервером, возвращаемый функцией ftp_connect() или ftp_ssl_connect().

Предопределенные константы

Перечисленные ниже константы определены данным расширением и могут быть доступны только в том случае, если PHP был собран с поддержкой этого расширения или же в том случае, если данное расширение подгружается во время выполнения.

FTP_ASCII (integer)
FTP_TEXT (integer)
FTP_BINARY (integer)
FTP_IMAGE (integer)
FTP_TIMEOUT_SEC (integer): Дополнительная информация доступна в описании функции ftp_set_option().

Следующие константы появились в PHP 4.3.0.

FTP_AUTOSEEK (integer): Дополнительная информация доступна в описании функции ftp_set_option().
FTP_AUTORESUME (integer): Автоматически определять позицию в файле, с которой начинается докачка при использовании команд GET и PUT (имеет смысл только совместно с FTP_AUTOSEEK)
FTP_FAILED (integer): Асинхронная операция завершилась неудачно
FTP_FINISHED (integer): Асинхронная операция окончена
FTP_MOREDATA (integer): Асинхронная операция еще не завершена

Примеры

Пример 1. Пример использования функций FTP

<?php // установка соединения $conn_id = ftp_connect($ftp_server); // вход с именем пользователя и паролем $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // проверка соединения if ((!$conn_id) || (!$login_result)) { echo "Не удалось установить соединение с FTP сервером!"; echo "Попытка подключения к серверу $ftp_server под именем $ftp_user_name!"; exit; } else { echo "Установлено соединение с FTP сервером $ftp_server под именем $ftp_user_name"; } // закачивание файла $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); // проверка результата if (!$upload) { echo "Не удалось закачать файл!"; } else { echo "Файл $source_file закачен на $ftp_server под именем $destination_file"; } // закрытие соединения ftp_close($conn_id); ?>

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 />";

    }

/*

    // try to delete $file

    if (ftp_delete($conn_id, $destination_file)) {

        echo "$destination_file has been deleted!\n";

    } else {

        echo "Could not delete $destination_file!\n";

    }

*/

ftp_close($conn_id); // close the FTP stream

}

?>

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



<?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 />";

        echo "Attempted to connect to $ftp_server for user $ftp_user_name";

        exit;

    } else {

        echo "Connected to $ftp_server, for user $ftp_user_name <br />";

    }



    $upload = ftp_put($conn_id, $destination_file, $local_file, FTP_BINARY);  // Upload the File

    

    // Verify Upload Status

    if (!$upload) {

        echo "<h2>FTP upload of ".$_FILES['txt_file']['name']." has failed!</h2><br /><br />";

    } else {

        echo "Success!<br />" . $_FILES['txt_file']['name'] . " has been uploaded to " . $ftp_server . $destination_file . "!<br /><br />";

    }



    ftp_close($conn_id); // Close the FTP Connection

}

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.

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;

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

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);

}

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

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

Check http://nanoftpd.sourceforge.net/ for a FTP server written in PHP.

Supports Passive and Active FTP, and all other standard FTP commands as decribed in RFC959.

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 );
