Here is an example of how to send a file with SFTP:



<?php



class SFTPConnection

{

    private $connection;

    private $sftp;



    public function __construct($host, $port=22)

    {

        $this->connection = @ssh2_connect($host, $port);

        if (! $this->connection)

            throw new Exception("Could not connect to $host on port $port.");

    }



    public function login($username, $password)

    {

        if (! @ssh2_auth_password($this->connection, $username, $password))

            throw new Exception("Could not authenticate with username $username " .

                                "and password $password.");



        $this->sftp = @ssh2_sftp($this->connection);

        if (! $this->sftp)

            throw new Exception("Could not initialize SFTP subsystem.");

    }



    public function uploadFile($local_file, $remote_file)

    {

        $sftp = $this->sftp;

        $stream = @fopen("ssh2.sftp://$sftp$remote_file", 'w');



        if (! $stream)

            throw new Exception("Could not open file: $remote_file");



        $data_to_send = @file_get_contents($local_file);

        if ($data_to_send === false)

            throw new Exception("Could not open local file: $local_file.");



        if (@fwrite($stream, $data_to_send) === false)

            throw new Exception("Could not send data from file: $local_file.");



        @fclose($stream);

    }

}



try

{

    $sftp = new SFTPConnection("localhost", 22);

    $sftp->login("username", "password");

    $sftp->uploadFile("/tmp/to_be_sent", "/tmp/to_be_received");

}

catch (Exception $e)

{

    echo $e->getMessage() . "\n";

}



?>
