(PHP Extension) FTP Download Binary File to a Stream

Demonstrates how to FTP download a binary file to a Chilkat stream.

Note: This example requires Chilkat v9.5.0.67 or greater.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example assumes the Chilkat FTP2 API to have been previously unlocked.
// See FTP2 Unlock Sample for sample code.

$ftp = new CkFtp2();

$ftp->put_Hostname('www.my-ftp-server.com');
$ftp->put_Username('mFtpLogin');
$ftp->put_Password('myFtpPassword');
$ftp->put_AuthTls(true);
$ftp->put_Passive(true);

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

// We'll read the incoming data chunk-by-chunk and write to an output file.
$fac = new CkFileAccess();
$success = $fac->OpenForWrite('qa_output/penguins2.jpg');
if ($success != true) {
    print $fac->lastErrorText() . "\n";
    exit;
}

$streamObj = new CkStream();

// Create a task to do the FTP download.
// t is a CkTask
$t = $ftp->GetFileToStreamAsync('penguins2.jpg',$streamObj);
if ($ftp->get_LastMethodSuccess() != true) {
    print $ftp->lastErrorText() . "\n";
    exit;
}

// Start the task in a background thread.
$t->Run();

$bd = new CkBinData();
while ($streamObj->get_EndOfStream() != true) {
    // Get the next chunk of JPG bytes.
    $streamObj->ReadBd($bd);
    // Do something with it..
    // In this simple example, we'll just write to the file.
    $fac->FileWriteBd($bd,0,0);
    // Clear for the next read.
    $bd->Clear();
}

$fac->FileClose();

print 'Success.' . "\n";
