<?php

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Upload')

// Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
// that will process the HTTP Upload.

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

// Begin the HTTP upload in a background thread:
$success = $upload->BeginUpload();
if ($success != 1) {
    print $upload->LastErrorText . "\n";

// Wait for the upload to finish.
// Print the progress as we wait...

    // 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->PercentUploaded . '% ' . $upload->NumBytesSent . '/' . $upload->TotalUploadSize . "\n";

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