// 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.Ftp2')
$ftp = new COM("Chilkat.Ftp2");

// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to connecting:
// The SOCKS hostname may be a domain name or 
// IP address:
$ftp->SocksHostname = 'www.mysocksproxyserver.com';
$ftp->SocksPort = 1080;
$ftp->SocksUsername = 'myProxyLogin';
$ftp->SocksPassword = 'myProxyPassword';
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
$ftp->SocksVersion = 5;
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Connect and login to the FTP server.

// This step is only necessary if the file is not in the root directory
// for the FTP account.
