FTP Automatic Post-Connect Commands

Demonstrates the AutoFeat, AutoSyst, AutoOptsUtf8, and AutoXcrc properties, which control commands Chilkat issues automatically around connecting and transferring.

Background: Chilkat normally probes and adapts to a server on its own: AutoFeat discovers capabilities with FEAT, AutoSyst learns the OS type to parse legacy listings, and AutoOptsUtf8 enables UTF-8 filenames when the server advertises it. These are on by default and rarely worth changing. AutoXcrc is the exception worth enabling deliberately — it verifies each upload with the server's XCRC checksum, catching corruption automatically where supported.

// These auto-* properties control commands Chilkat sends automatically after connecting.  They
// are on/off by default as noted, and are rarely changed.

// AutoFeat (default true): automatically send FEAT to discover server capabilities.
$ftp->AutoFeat = true;

// AutoSyst (default true): automatically send SYST after login to learn the server OS type.
$ftp->AutoSyst = true;

// AutoOptsUtf8 (default true): send OPTS UTF8 ON when the FEAT response advertises UTF8.
$ftp->AutoOptsUtf8 = true;

// AutoXcrc (default false): request an XCRC checksum after each upload and treat a mismatch as
// a failure, giving automatic post-upload verification where the server supports XCRC.
$ftp->AutoXcrc = true;

// Normally you would not hard-code the password in source.  You should instead obtain it
// from an interactive prompt, environment variable, or a secrets vault.
