Introducing Zend_Cloud (cont'd)

Once connected you can begin using the unified interface to interact with the S3 storage service. For instance, to store a text file you would use the $storage object's storeItem() method, like this:
...
$book = file_get_contents('/var/www/example.com/books/book.txt');
$result = $storage->storeItem(
  '/books/book.txt', 
  $data, 
  array(
    Zend_Cloud_StorageService_Adapter_S3::BUCKET_NAME => "wjgilmore"
  )
);
With the file stored on S3, you can later retrieve it like this:
$book = $storage->fetchItem("/books/book.txt", 
      array(Zend_Cloud_StorageService_Adapter_S3::BUCKET_NAME => "wjgilmore"));
Incidentally, it's possible to set a default bucket name within the factory, allowing you to forego passing the name to the storeItem() and fetchItem() methods. Of course, the greatest strength of the Simple Cloud API is the unified API. For instance, switching over from S3 to Windows Azure is done simply by refactoring the factory, as demonstrated here:
$storage = Zend_Cloud_StorageService_Factory::getAdapter(array(
  Zend_Cloud_StorageService_Factory::STORAGE_ADAPTER_KEY       => 'Zend_Cloud_StorageService_Adapter_WindowsAzure',
  Zend_Cloud_StorageService_Adapter_WindowsAzure::ACCOUNT_NAME => 'YOUR_ACCOUNT_NAME',
  Zend_Cloud_StorageService_Adapter_WindowsAzure::ACCOUNT_KEY  => 'YOUR_SECRET_KEY',
  Zend_Cloud_StorageService_Adapter_WindowsAzure::CONTAINER    => 'YOUR_CONTAINER',
  Zend_Cloud_StorageService_Adapter_WindowsAzure::HOST         => 'blob.core.windows.net'
));

$book = file_get_contents('/var/www/example.com/books/book.txt');
$result = $storage->storeItem(
  '/books/book.txt', 
  $data
);
