<?php

$upload = new COM("Chilkat.Upload");

//  Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
//  that will process the HTTP Upload.
//  You must change these values to your hostname/path.
$upload->Hostname = 'www.yourwebserver123.com';
$upload->Path = '/receiveUpload.asp';

//  To upload via HTTPS, you only need to set the port
//  and "Ssl" property.  All other programming remains the same:
$upload->Ssl = true;
$upload->Port = 443;

//  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 HTTPS upload in a background thread:
$success = $upload->BeginUpload();
if ($success != true) {
    print $upload->lastErrorText() . "\n";
}
else {
    print 'Files uploaded!' . "\n";
}

//  Wait for the upload to finish.
//  Print the progress as we wait...
while (($upload->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->PercentUploaded . '% '
         . $upload->NumBytesSent . '/' . $upload->TotalUploadSize . "\n";

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

}

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