// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$sftp = new CkSFtp();

// Set some timeouts, in milliseconds:
$sftp->put_ConnectTimeoutMs(15000);
$sftp->put_IdleTimeoutMs(15000);

// 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 != true) {
    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 != true) {
    print $sftp->lastErrorText() . "\n";
    exit;
}

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

// Download the file:

$localFilePath = 'c:/temp/hamlet.xml';
// Note: The remote filepath may be an absolute filepath,
// a relative filepath, or simply a filename.  
// Relative filepaths are always relative to the home directory
// of the SFTP/SSH user account.  There is no such thing
// as "current remote directory" in the SFTP protocol. 
// A filename with no path implies that the file is located
// in the SFTP user account's home directory.
$remoteFilePath = 'subdir1/subdir2/hamlet.xml';
