First and foremost, update to the latest release of php-opencloud, currently 1.7.
Next, included sample code for the Object Store is located here, but doesn't include what you were looking to do.
The following code, given a path, will iterate through your containers and save the objects from your container to the destination path ($savePath). If the object already exists in that path, it will be skipped. This version includes output indicating success or failure for each object. Give this a try and let me know if you have any issues.
NOTE: Keep in mind that Rackspace's Cloud Files, Object Store, is handled on a per Datacenter basis so files stored in a container in ORD would be accessible only if you connect to the objectStoreService in ORD.
<?php
require 'vendor/autoload.php';
$authURL = 'https://identity.api.rackspacecloud.com/v2.0/';
$credentials = array(
'username' => 'YOUR_USERNAME',
'apiKey' => 'YOUR_API_KEY',
);
$savePath = '/path/to/files/';
$connection = new \OpenCloud\Rackspace($authURL, $credentials);
$objstore = $connection->objectStoreService('cloudFiles', 'ORD');
// get our containers
print("Containers:\n");
$conlist = $objstore->listContainers();
//var_dump($conlist);
while($container = $conlist->Next()) {
printf("*** %s\n", $container->name);
if($container->name == 'test2')
{
$files = $container->ObjectList();
while($o = $files->Next())
{
$file_name = $o->getName();
// Get our object
$file = $container->getObject($file_name);
printf("** %s\n", $file->getName());
// Let's save this file
echo "* Saving object\n";
if(file_exists($savePath.$file_name))
{
echo "* File already exists! SKIPPING\n\n";
}
else
{
if (!$fp = @fopen($savePath.$file_name, "wb")) {
throw new OpenCloud\Common\Exceptions\IOError(sprintf(
'Could not open file [%s] for writing',
$savePath.$file_name
));
}
//$retval = fwrite($fp, $o->getContent());
if (fwrite($fp, $file->getContent()) === FALSE) {
echo "* ERROR - Cannot write to file ($savePath.$file_name)\n\n";
}
else
{
echo "* File successfully written\n\n";
}
}
}
}
}
Output:
