(PHP ActiveX) Co:Z SFTP Binary File Download (from z/OS IBM Mainframe)

Demonstrates how to download a binary file, such as a .zip, from a Co:Z SFTP server on a z/OS IBM Mainframe.

Note: This requires Chilkat v9.5.0.76 or greater.

// This example requires 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");

// Connect to the SSH server.  
$hostname = 'sftp.example.com';

// To download a binary file from the Co:Z SFTP server, 
// we must switch to binary mode in the following unconventional way.
// We pretend to fetch a directory listing for "/+mode=binary"
// This has the effect of putting the server in binary mode for transfers.
$handle = $sftp->openDir('/+mode=binary');
if ($sftp->LastMethodSuccess != 1) {
    print $sftp->LastErrorText . "\n";
    exit;

// Download the "directory listing" (but it's not actually a directory listing, and we'll just discard it.)
// dirListing is a Chilkat.SFtpDir
$dirListing = $sftp->ReadDir($handle);
if ($sftp->LastMethodSuccess != 1) {
    print $sftp->LastErrorText . "\n";

// Close the directory handle:

// Download the binary file:
