PHP S3 Examples
|
|
===============
|
|
|
|
Creating a Connection
|
|
---------------------
|
|
|
|
This creates a connection so that you can interact with the server.
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
define('AWS_KEY', 'place access key here');
|
|
define('AWS_SECRET_KEY', 'place secret key here');
|
|
define('AWS_CANONICAL_ID', 'your DHO Username');
|
|
define('AWS_CANONICAL_NAME', 'Also your DHO Username!');
|
|
$HOST = 'objects.dreamhost.com';
|
|
|
|
// require the amazon sdk for php library
|
|
require_once 'AWSSDKforPHP/sdk.class.php';
|
|
|
|
// Instantiate the S3 class and point it at the desired host
|
|
$Connection = new AmazonS3();
|
|
$Connection->set_hostname($HOST);
|
|
$Connection->allow_hostname_override(false);
|
|
|
|
// Set the S3 class to use objects.dreamhost.com/bucket
|
|
// instead of bucket.objects.dreamhost.com
|
|
$Connection->enable_path_style();
|
|
|
|
|
|
Listing Owned Buckets
|
|
---------------------
|
|
This gets a list of CFSimpleXML objects representing buckets that you
|
|
own. This also prints out the bucket name and creation date of each
|
|
bucket.
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$ListResponse = $Connection->list_buckets();
|
|
$Buckets = $ListResponse->body->Buckets->Bucket;
|
|
foreach ($Buckets as $Bucket) {
|
|
echo $Bucket->Name . "\t" . $Bucket->CreationDate . "\n";
|
|
}
|
|
|
|
The output will look something like this::
|
|
|
|
mahbuckat1 2011-04-21T18:05:39.000Z
|
|
mahbuckat2 2011-04-21T18:05:48.000Z
|
|
mahbuckat3 2011-04-21T18:07:18.000Z
|
|
|
|
|
|
Creating a Bucket
|
|
-----------------
|
|
|
|
This creates a new bucket called ``my-new-bucket`` and returns a
|
|
``CFResponse`` object.
|
|
|
|
.. note::
|
|
|
|
This command requires a region as the second argument,
|
|
so we use ``AmazonS3::REGION_US_E1``, because this constant is ``''``
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$Connection->create_bucket('my-new-bucket', AmazonS3::REGION_US_E1);
|
|
|
|
|
|
List a Bucket's Content
|
|
-----------------------
|
|
|
|
This gets an array of ``CFSimpleXML`` objects representing the objects
|
|
in the bucket. This then prints out each object's name, the file size,
|
|
and last modified date.
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$ObjectsListResponse = $Connection->list_objects($bucketname);
|
|
$Objects = $ObjectsListResponse->body->Contents;
|
|
foreach ($Objects as $Object) {
|
|
echo $Object->Key . "\t" . $Object->Size . "\t" . $Object->LastModified . "\n";
|
|
}
|
|
|
|
.. note::
|
|
|
|
If there are more than 1000 objects in this bucket,
|
|
you need to check $ObjectListResponse->body->isTruncated
|
|
and run again with the name of the last key listed.
|
|
Keep doing this until isTruncated is not true.
|
|
|
|
The output will look something like this if the bucket has some files::
|
|
|
|
myphoto1.jpg 251262 2011-08-08T21:35:48.000Z
|
|
myphoto2.jpg 262518 2011-08-08T21:38:01.000Z
|
|
|
|
|
|
Deleting a Bucket
|
|
-----------------
|
|
|
|
This deletes the bucket called ``my-old-bucket`` and returns a
|
|
``CFResponse`` object
|
|
|
|
.. note::
|
|
|
|
The Bucket must be empty! Otherwise it won't work!
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$Connection->delete_bucket('my-old-bucket');
|
|
|
|
|
|
Forced Delte for Non-empty Buckets
|
|
----------------------------------
|
|
|
|
This will delete the bucket even if it is not empty.
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$Connection->delete_bucket('my-old-bucket', 1);
|
|
|
|
|
|
Creating an Object
|
|
------------------
|
|
|
|
This creates an object ``hello.txt`` with the string ``"Hello World!"``
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$Connection->create_object('my-bucket-name', 'hello.txt', array(
|
|
'body' => "Hello World!",
|
|
));
|
|
|
|
|
|
Change an Object's ACL
|
|
----------------------
|
|
|
|
This makes the object ``hello.txt`` to be publicly readable and
|
|
``secret_plans.txt`` to be private.
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$Connection->set_object_acl('my-bucket-name', 'hello.txt', AmazonS3::ACL_PUBLIC);
|
|
$Connection->set_object_acl('my-bucket-name', 'secret_plans.txt', AmazonS3::ACL_PRIVATE);
|
|
|
|
|
|
Delete an Object
|
|
----------------
|
|
|
|
This deletes the object ``goodbye.txt``
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$Connection->delete_object('my-bucket-name', 'goodbye.txt');
|
|
|
|
|
|
Download an Object (to a file)
|
|
------------------------------
|
|
|
|
This downloads the object ``poetry.pdf`` and saves it in
|
|
``/home/larry/documents/``
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
$FileHandle = fopen('/home/larry/documents/poetry.pdf', 'w+');
|
|
$Connection->get_object('my-bucket-name', 'poetry.pdf', array(
|
|
'fileDownload' => $FileHandle,
|
|
));
|
|
|
|
|
|
Generate Object Download URLs (signed and unsigned)
|
|
---------------------------------------------------
|
|
|
|
This generates an unsigned download URL for ``hello.txt``.
|
|
This works because we made ``hello.txt`` public by setting
|
|
the ACL above. This then generates a signed download URL
|
|
for ``secret_plans.txt`` that will work for 1 hour.
|
|
Signed download URLs will work for the time period even
|
|
if the object is private (when the time period is up,
|
|
the URL will stop working).
|
|
|
|
.. code-block:: php
|
|
|
|
<?php
|
|
my $plans_url = $Connection->get_object_url('my-bucket-name', 'hello.txt');
|
|
echo $plans_url . "\n";
|
|
my $secret_url = $Connection->get_object_url('my-bucket-name', 'secret_plans.txt', '1 hour');
|
|
echo $secret_url . "\n";
|
|
|
|
The output of this will look something like::
|
|
|
|
http://objects.dreamhost.com/my-bucket-name/hello.txt
|
|
http://objects.dreamhost.com/my-bucket-name/secret_plans.txt?Signature=XXXXXXXXXXXXXXXXXXXXXXXXXXX&Expires=1316027075&AWSAccessKeyId=XXXXXXXXXXXXXXXXXXX
