Rackspace Cloud FIles Bulk Delete objects prefixed/* wildcard php sdk

Hi Guys

Rackspace cloud files is an awesome file storage system, We upload a file and can make it publicly available through their CDN.

While I use Cloud files in pretty much all my projects at work or personal stuff, one thing that I did today was to delete objects with specific prefix

e.g.

Lets say I have these objects under container “jcorg”

• hello
• hello1
• hello2
• anothervaluableobject

and I want to delete all objects whose name starts with hello

Here is a code snippet that will be handy for you

Language: PHP
API link: https://github.com/rackspace/php-opencloud

and of course you can use equivalent code in other language SDKs too

Code Snippet

Let me give you a brief overview to you

1. First we are creating a connection to Rackspace server, depending on which region you are in you will use either RACKSPACE_US or RACKSPACE_UK to authenticate your request.
   
   $connection = new \OpenCloud\Rackspace(AUTHURL_US_OR_UK, array('username' => USERNAME, 'apiKey' => APIKEY));

   1 2 3

   $connection = new \OpenCloud\Rackspace(AUTHURL_US_OR_UK,                     array('username' => USERNAME,                         'apiKey' => APIKEY));

2. Then we are connection to our object store
   
   // now, connect to the ObjectStore service $objstore = $connection->objectStoreService('cloudFiles', 'SYD'); $container = $objstore->getContainer("jcorg");

   1 2 3

   // now, connect to the ObjectStore service                 $objstore = $connection->objectStoreService('cloudFiles', 'SYD');                 $container = $objstore->getContainer("jcorg");

3. Then we are getting hold of object list where name or an object starts with “hello”
   
   $options = array( 'prefix' => 'hello' ); $objects = $container->objectList($options);

   1 2 3 4

   $options = array(                         'prefix' => 'hello'                     );                     $objects = $container->objectList($options);

4. Finally we are iterating on objects found and deleting them. You can check object name here to just to filter them out before you process them for deletion
   
   foreach ($objects as $object) { /** @var $object OpenCloud\ObjectStore\Resource\DataObject **/ $object->delete(); }

   1 2 3 4

   foreach ($objects as $object) {                         /** @var $object OpenCloud\ObjectStore\Resource\DataObject  **/                         $object->delete();                     }

I hope this makes sense, but just in case if you have a question, do leave your comment.
