Demonstrates how to restart / resume an FTP upload. PHP Extension

<?php

include("chilkat.php");

$success = false;

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

$ftp = new CkFtp2();

$ftp->put_Hostname('ftp.example.com');
$ftp->put_Username('login');
$ftp->put_Password('password');

// Connect and login to the FTP server.
$success = $ftp->Connect();
if ($success != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

// Change to the remote directory where the file will be uploaded.
$success = $ftp->ChangeRemoteDir('temp');
if ($success != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

// In this example, assume that a previous FTP upload failed,
// and the incomplete file (bigFile.zip) exists on the FTP server.
// You only need to set the RestartNext property to resume
// the upload.  When RestartNext is set, the next call
// to PutFile (or PutFileFromBinaryData, PutFileFromTextData)
// will automatically resume the upload from the point of failure.
// (The way it works is that the FTP component sends a "SIZE"
// command to the FTP server to find out how many bytes of
// the file already exist on the server.  It then begins
// uploading from that point.

// Note: After PutFile is called, the RestartNext property
// is automatically set to false.
$ftp->put_RestartNext(true);

// Upload a file with restart.
$localFilename = 'bigFile.zip';
$remoteFilename = 'bigFile.zip';

$success = $ftp->PutFile($localFilename,$remoteFilename);
if ($success != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

$success = $ftp->Disconnect();

print 'File Uploaded!' . "\n";
