How to send a file using FTP?

Question

I have a sample CSV file and want to send it to another server using FTP. I have successfully connected FTP but couldn't able to send the file.

In the FTP where I want to send, there are 2 folders named Import and Export. I have checked those folders but I can't see the file which I sent. I didn't get any error as well. So, I'm not sure, where am I wrong.

In order to send the file using FTP, I have followed the below link:

https://www.magestore.com/magento-2-tutorial/how-to-upload-file-to-ftp-server-by-coding-in-magento-2/

Would anyone please help me to resolve this issue?

Code:

<?php
use Magento\Framework\App\Bootstrap;
require __DIR__ . '/app/bootstrap.php';

$bootstrap = Bootstrap::create(BP, $_SERVER);

$objectManager = $bootstrap->getObjectManager();

$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');

$sftp = $objectManager->create('Magento\Framework\Filesystem\Io\Sftp');
$open =  $sftp->open(
                    array(
                        'host' => 'hostname',
                        'username' => 'xyz',
                        'password' => 'pwd',
                        'port' =>22,
                        'passive' => true
                    )
                );

if ($open) {
      $fileName = ‘sample.csv’;
      $content = file_get_contents(DirectoryList::VAR_DIR . '/' . $fileName);
      $this->ftp->write(self::FILE_NAME_ON_FTP, $content);
      $this->ftp->close();
 }

 if(is_null($connection)){
      echo "true";
      //Here is code ....
 }else{
      echo "false";
 }

Please replace your code with below content

<?php
use Magento\Framework\App\Bootstrap;
use Magento\Framework\Filesystem\DirectoryList;
require __DIR__ . '/app/bootstrap.php';

$bootstrap = Bootstrap::create(BP, $_SERVER);

$objectManager = $bootstrap->getObjectManager();

$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');

$directory = $objectManager->get('\Magento\Framework\Filesystem\DirectoryList');

$sftp = $objectManager->create('Magento\Framework\Filesystem\Io\Sftp');
$open =  $sftp->open(
            array(
                'host' => '',
                'username' => '',
                'password' => '',
                'port' =>22,
                'passive' => true
            )
        );

$fileName = 'sample.csv';
$content = file_get_contents($directory->getPath('var') . '/' . $fileName);
$sftp->write('/Import/test1.csv', $content);
$sftp->close();
echo "File uploaded..!";

Hope this will help you!

Please replace your code with below code and check:

<?php
use Magento\Framework\App\Bootstrap;
use Magento\Framework\App\Filesystem\DirectoryList;
require __DIR__ . '/app/bootstrap.php';

$bootstrap = Bootstrap::create(BP, $_SERVER);

$objectManager = $bootstrap->getObjectManager();

$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');

$sftp = $objectManager->create('Magento\Framework\Filesystem\Io\Sftp');
$open =  $sftp->open(
                    array(
                        'host' => 'hostname',
                        'username' => 'xyz',
                        'password' => 'pwd',
                    )
                );

if ($open) {
      $fileName = 'sample.csv'; // create sample.csv file in var folder
      $content = file_get_contents(DirectoryList::VAR_DIR . '/' . $fileName);
      $sftp->write('yourprojectpath/test.csv', $content); //please give full path of your hosting root project path and create first test.csv file
      $sftp->close();
 } else {
    echo "Something wrong in hosting detail";
 }

please replace code in below core file or override in your module. because open function nothing to return. we need to return true when our hosting details are true

/vendor/magento/framework/Filesystem/Io/Sftp.php

From :

public function open(array $args = [])
    {
        if (!isset($args['timeout'])) {
            $args['timeout'] = self::REMOTE_TIMEOUT;
        }
        if (strpos($args['host'], ':') !== false) {
            list($host, $port) = explode(':', $args['host'], 2);
        } else {
            $host = $args['host'];
            $port = self::SSH2_PORT;
        }
        $this->_connection = new \phpseclib\Net\SFTP($host, $port, $args['timeout']);
        if (!$this->_connection->login($args['username'], $args['password'])) {
            throw new \Exception(
                sprintf("Unable to open SFTP connection as %s@%s", $args['username'], $args['host'])
            );
        }
    }

To :

public function open(array $args = [])
    {
        if (!isset($args['timeout'])) {
            $args['timeout'] = self::REMOTE_TIMEOUT;
        }
        if (strpos($args['host'], ':') !== false) {
            list($host, $port) = explode(':', $args['host'], 2);
        } else {
            $host = $args['host'];
            $port = self::SSH2_PORT;
        }
        $this->_connection = new \phpseclib\Net\SFTP($host, $port, $args['timeout']);
        if (!$this->_connection->login($args['username'], $args['password'])) {
            throw new \Exception(
                sprintf("Unable to open SFTP connection as %s@%s", $args['username'], $args['host'])
            );
        }
        return true;
    }
