(PHP ActiveX) SFTP Upload from Local Filesystem

Demonstrates how to upload a file to an SSH server. There are no limitations on file size, and the file is streamed directly from the local filesystem.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.SFtp')
$sftp = new COM("Chilkat.SFtp");

// Set some timeouts, in milliseconds:
$sftp->ConnectTimeoutMs = 5000;
$sftp->IdleTimeoutMs = 10000;

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
$hostname = 'sftp.example.com';
$port = 22;
$success = $sftp->Connect($hostname,$port);
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
$success = $sftp->AuthenticatePw('myLogin','myPassword');
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// After authenticating, the SFTP subsystem must be initialized:
$success = $sftp->InitializeSftp();
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Open a file for writing on the SSH server.
// If the file already exists, it is overwritten.
// (Specify "createNew" instead of "createTruncate" to
// prevent overwriting existing files.)
$handle = $sftp->openFile('hamlet.xml','writeOnly','createTruncate');
if ($sftp->LastMethodSuccess != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Upload from the local file to the SSH server.
$success = $sftp->UploadFile($handle,'c:/temp/hamlet.xml');
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// -----------------------------------------------------------------------------
// This is important.  You must close the handle on the server.
// Otherwise open handles will accumulate on the server until eventually a limit
// is reached and the server will fail on a call to OpenFile.
// -----------------------------------------------------------------------------

// Close the file.
$success = $sftp->CloseHandle($handle);
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
