FTP Sync Download Tree w/ Must-Match Constraints

See more FTP Examples

Demonstrates how synchronize a directory tree in the download direction, but only for files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Chilkat2 PHP

<?php

use Chilkat2\Ftp2;
use Chilkat2\StringTable;

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

$ftp = new Ftp2();

$ftp->Hostname = 'ftp.something.com';
$ftp->Username = 'my_login';
$ftp->Password = 'my_password';

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

    // Set the current remote directory to the root of
    // the tree to be downloaded.
    $ftp->ChangeRemoteDir('/subDir1');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// Possible synchronization modes are:
// mode=0: Download all files
// mode=1: Download all files that do not exist on the local filesystem.
// mode=2: Download newer or non-existant files.
// mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server..
// mode=5: Download only missing files or files with size differences.
// mode=6: Same as mode 5, but also download newer files.

// This example will download all files, but only those files having filenames
// that match *.gif and *.eml

// Imagine our remote directory tree has these files and directories:

//     accentedLatin1.txt
//     accentedUtf8.txt
//     alice.key
//     anter_cert.pem
//     chiliPepper.gif
//     helloWorld.pdf
//     abc/chiliPepper.gif
//     abc/ghk/
//     data/chiliPepper.gif
//     data/xyz/dkimHtmlBody.txt
//     data/xyz/dkimVerifyTest.eml
//     data/xyz/emailForCreateDsn.eml
//     text/frenchUtf8.txt
//     text/helloWorld.txt
//     text/PolishEmailBody.txt
//     text/something/

// Indicate that we only want to create auto-create local directories (if needed)
// for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
// true, then the corresponding local directory is created for each remote directory
// traversed regardless of whether files within are downloaded.
$ftp->SyncCreateAllLocalDirs = false;

$ftp->SyncMustMatch = '*.eml; *.gif';
$mode = 0;
try {
    $ftp->SyncLocalTree('c:/temp/subDir1', $mode);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

$ftp->Disconnect();

// Show the files downloaded.
$st = new StringTable();
$ftp->GetSyncedFiles($st);

$numFiles = $st->Count;
$i = 0;
while ($i < $numFiles) {
    echo $st->StringAt($i), "\n";
    $i = $i + 1;
}

// Output showing the files downloaded:

// chiliPepper.gif
// abc/chiliPepper.gif
// data/chiliPepper.gif
// data/xyz/dkimVerifyTest.eml
// data/xyz/emailForCreateDsn.eml
