Faster Rackspace cloud upload - php

Question

I have used to the Rackspace API to upload files to the RackSpace cloud. But this method seems to be a little on the slow side. Is there a better or faster way to upload a file to the cloud(curl, http adapters, etc)?
I am currently uploading with PHP and using the provided API.

Answer 1

Here is my solution how to make it fast:
I'm uploading only missing files using simple PHP script below. Thanks to it I do it in just one click and in just a few seconds.
PHP source code:
function UploadMissingFilesToRackFileCDN($file_paths_to_upload, $b_force_upload = false)
{
include_once("cloudfiles.php");
// Connect to Rackspace
$username = cloudfile_username; // username
echo "Connecting to CDN..." . date("H:i:s") . "<br>"; ob_flush();
$key = cloudfile_api_key; // api key
$auth = new CF_Authentication($username, $key);
$auth->authenticate();
$conn = new CF_Connection($auth);
echo " Connected!" . date("H:i:s") . "<br>"; ob_flush();
// Get the container we want to use
$container_name = 'vladonai';//'test_container';
echo "Obtaining container $container_name..." . date("H:i:s") . "<br>"; ob_flush();
$container = $conn->get_container($container_name);
echo " The container is obtained." . date("H:i:s") . "<br>"; ob_flush();
if (!$b_force_upload)
{
echo "Receiving container objects list..." . date("H:i:s") . "<br>"; ob_flush();
$existing_object_names = $container->list_objects();
$existing_files_count = count($existing_object_names);
echo " Objects list obtained: $existing_files_count." . date("H:i:s") . "<br>"; ob_flush();
$existing_object_names_text .= "\r\n";
foreach ($existing_object_names as $obj_name)
{
$existing_object_names_text .= $obj_name . "\r\n";
}
}
// upload files to Rackspace
$uploaded_file_n = 0;
$skipped_file_n = 0;
$errors_count = 0;
foreach ($file_paths_to_upload as $localfile_path => $file_info)
{
$filename = basename($localfile_path);
if (!file_exists($localfile_path))
{
echo "<font color=red>Error! File $localfile_path doesn't exists!</font>" . date("H:i:s") . "<br>"; ob_flush();
$errors_count ++;
} else
if (is_dir($localfile_path))
{
//simply skip it
} else
if (strpos($existing_object_names_text, "\r\n" . $filename . "\r\n") !== false)
{
//file is already uploaded to CDN (at least file name is present there). Would be good to have date/size checked, but CDN api has no such feature
//echo "<font color=gray>Skipped file $localfile_path - it already exists!</font><br>"; ob_flush();
$skipped_file_n ++;
} else
{
echo "<font color=green>Uploading file $localfile_path (file #$uploaded_file_n)..." . date("H:i:s") . "</font><br>"; ob_flush();
try
{
$object = $container->create_object($filename);
$object->load_from_filename($localfile_path);
$uploaded_file_n ++;
}
catch (Exception $e)
{
echo "<font color=red>Error! Caught exception: ", $e->getMessage(), " on uploading file <strong>$localfile_path</strong>!</font>" . date("H:i:s") . "<br>"; ob_flush();
$errors_count ++;
}
}
// if ($uploaded_file_n >= 10)
// break;
}
echo "Done! $uploaded_file_n files uploaded. Disconnecting :)" . date("H:i:s") . "<br>"; ob_flush();
echo "Skipped files: $skipped_file_n<br>"; ob_flush();
if ($errors_count > 0)
echo "<font color=red>Erorrs: $errors_count</font><br>"; ob_flush();
