Restart/Resume FTP Upload

See more FTP Examples

Demonstrates how to restart / resume an FTP upload. Chilkat2 PHP

<?php

use Chilkat2\Ftp2;

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

$ftp = new Ftp2();

$ftp->Hostname = 'ftp.example.com';
$ftp->Username = 'login';
$ftp->Password = 'password';

// Connect and login to the FTP server.
try {
    $ftp->Connect();

    // Change to the remote directory where the file will be uploaded.
    $ftp->ChangeRemoteDir('temp');

    // 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->RestartNext = true;

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

    $ftp->PutFile($localFilename, $remoteFilename);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

$ftp->Disconnect();

echo "File Uploaded!\n";
