<?php

$ftp = new COM("Chilkat.Ftp2");

//  Any string unlocks the component for the 1st 30-days.
$success = $ftp->UnlockComponent('Anything for 30-day trial');
if ($success != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

$ftp->Hostname = 'www.example-code.com';
$ftp->Username = '****';
$ftp->Password = '****';

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

//  Note: It may be tempting to call MGetFiles(pattern,localDir)
//  followed by a call to DeleteMatching(pattern), however,
//  if new files are uploaded to the FTP server while MGetFiles
//  is running, those files will be deleted by DeleteMatching.

//  Instead, it's best to set the ListPattern and then iterate
//  over each file...

//  Set the ListPattern = "*.xml" to match all XML files.
$ftp->ListPattern = '*.xml';

//  NumFilesAndDirs contains the number of files and sub-directories
//  matching the ListPattern in the current remote directory.
//  The first time it is accessed after changing ListPattern,
//  or after calling ChangeRemoteDir, a snapshot of the directory
//  listing is fetched and saved in memory. During this loop,
//  the value of NumFilesAndDirs will not change.

$n = $ftp->NumFilesAndDirs;
if ($n < 0) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

if ($n > 0) {
    for ($i = 0; $i <= $n - 1; $i++) {

        $fname = $ftp->getFilename($i);
        print $fname . "\n";

        //  Download the file into the current working directory.
        $success = $ftp->GetFile($fname,$fname);
        if ($success != true) {
            print $ftp->lastErrorText() . "\n";
            exit;
        }

        //  Now delete the file.
        $success = $ftp->DeleteRemoteFile($fname);
        if ($success != true) {
            print $ftp->lastErrorText() . "\n";
            exit;
        }

    }
