SFTP Upload - Synchronize Directory Tree

See more SFTP Examples

Demonstrates how to upload files to synchronize a local directory tree with a remote directory tree. The SyncTreeUpload method recursively descends a local directory tree and uploads files based on existence, last-mod date/time and/or size differences. Chilkat2 PHP

<?php

use Chilkat2\SFtp;

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

$sftp = new SFtp();

try {
    $sftp->Connect('my-ssh-server.com', 22);
    $sftp->AuthenticatePw('mySshLogin', 'mySshPassword');

    $sftp->InitializeSftp();

    // Synchronize (by uploading) the local directory tree rooted at "qa_data/sftpUploadTree"
    // with the remote directory tree rooted at "syncUploadTest"
    // Both directories are relative paths.  The remote directory
    // is relative to the HOME directory of the SSH user account.
    // The local directory is relative to the current working directory of the process.
    // It is also possible to use absolute paths.

    $remoteDir = 'syncUploadTest';
    $localDir = 'qa_data/sftpUploadTree';

    // Possible modes that can be passed to the SyncTreeUpload method are:
    // mode=0: Upload all files
    // mode=1: Upload all files that do not exist on the server.
    // mode=2: Upload newer or non-existant files.
    // mode=3: Upload only newer files. If a file does not already exist on the server, it is not uploaded.
    // mode=4: transfer missing files or files with size differences.
    // mode=5: same as mode 4, but also newer files.

    // This example will use mode 5 to upload missing, newer, or files with size differences.
    $mode = 5;
    // This example turns on recursion to synchronize the entire tree.
    // Recursion can be turned off to synchronize the files of a single directory.
    $recursive = true;
    $sftp->SyncTreeUpload($localDir, $remoteDir, $mode, $recursive);
