(PHP Extension) Bandwidth Throttled Asynchronous HTTP Upload

Demonstrates how to do an HTTP upload asynchronously in a background thread with limiting the rate to an approximate number of bytes/second. The only difference between this example and one without bandwidth throttling is that the BandwidthThrottleUp property is set.

<?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");

$upload = new CkUpload();

// Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
// that will process the HTTP Upload.
$upload->put_Hostname('www.mywebserver.com');
$upload->put_Path('/receiveUpload.aspx');

// Add one or more files to be uploaded.
$upload->AddFileReference('file1','dude.gif');
$upload->AddFileReference('file2','pigs.xml');
$upload->AddFileReference('file3','sample.doc');

// Set the BandwidthThrottleUp property to throttle to approx 64K/second
$upload->put_BandwidthThrottleUp(65536);

// Begin the HTTP upload in a background thread:
$success = $upload->BeginUpload();
if ($success != true) {
    print $upload->lastErrorText() . "\n";
}
else {
    print 'Upload started...' . "\n";
}

// Wait for the upload to finish.
// Print the progress as we wait...
while (($upload->get_UploadInProgress() == true)) {
    // We can abort the upload at any point by calling:
    // upload.AbortUpload();

    // Display the percentage complete and the number of bytes uploaded so far..
    // The total upload size will become set after the upload begins:
    print $upload->get_PercentUploaded() . '% ' . $upload->get_NumBytesSent() . '/' . $upload->get_TotalUploadSize() . "\n";

    // Sleep 2/10ths of a second.
    $upload->SleepMs(200);

}

// Did the upload succeed?
if ($upload->get_UploadSuccess() == true) {
    print 'Files uploaded!' . "\n";
