Amazon Web Services and the AWS SDK for PHP continue to put more power into the hands of PHP developers to build robust and scalable web applications. With version 2 of the SDK, developers now have an even more powerful library for interacting with AWS built on top of existing open source software like the Guzzle HTTP framework and the Symfony 2 Event Dispatcher. In this session you will learn about Amazon Web Services, how to use the AWS SDK for PHP, and how you can easily deploy and scale your applications to the cloud with AWS services, including AWS Elastic Beanstalk.

1. Amazon Web Services
for PHP Developers

2. Oh Hai! I'm Jeremy Lindblom!
• I work on the AWS SDK for PHP at
• Co-organizer of the Seattle PHP Meetup Group
• B.S. in Computer Science from
• @jeremeamia on
• I like to make funny faces

3. What is "The Cloud"?

4. Cloud computing
is the acquisition and use
of computing resources that
are delivered as a service on an
as-needed basis.

5. "The Cloud"
• Evolution of distributed computing and
Service-oriented Architecture (SOA).
• Benefits
– No upfront investment
– Low ongoing cost
– Flexible capacity
– Speed & agility
– Apps not ops
– Global reach
( http://aws.amazon.com/what-is-cloud-computing/ )

7. Bringing you the “The Cloud” since 2006.

8. Amazon Web Services offers a
complete set of infrastructure and
application services that enable
you to run virtually everything in
the cloud: from enterprise
applications and big data projects
to social games and mobile apps.

15. How do I use AWS?

16. AWS Console

17. AWS SDKs and Tools
PHP • Java • Python • .NET
Ruby • Node.js • iOS • Android
SDKs
Unified CLI • Visual Studio Plugin
Eclipse Plugin • PowerShell Tools
Tools

18. General SDK Features
• Suite of HTTP clients
• Input and output serialization
• Protocol normalization
• Authentication
• Error handling
• Language-specific conveniences
• Open source

19. The AWS SDK for PHP
http://github.com/aws/aws-sdk-php

20. Quick History
• Tarzan (Started by @skyzyx)
• CloudFusion
• AWS SDK for PHP [2010]
• AWS SDK for PHP 2 [Late 2012]

21. AWS SDK for PHP Features
• PHP 5.3+, PSR compliant
• Persistent connections, parallel requests
• Event hooks, plugins, and wire logging
• Simple array-style inputs and outputs
• Iterators, waiters, and batching helpers
• Higher-level abstractions

22. require
'vendor/autoload.php';
use
AwsS3S3Client;
$s3
=
S3Client::factory(array(
'key'
=>
'your-­‐aws-­‐access-­‐key-­‐id',
'secret'
=>
'your-­‐aws-­‐secret-­‐key',
));
$result
=
$s3-­‐>putObject(array(
'Bucket'
=>
'my-­‐cool-­‐photos',
'Key'
=>
'photo.jpg',
'Body'
=>
fopen('./photo.jpg',
'r')
));

23. Built on Guzzle
• Popular HTTP Library
– Goutte
– AWS SDK for PHP J
– Drupal 8
• Foundation of the SDK
• Symfony2 Events
• http://guzzlephp.org

24. Installing the PHP SDK
• Composer
• PEAR
• Downloadable Phar
• RPM/yum (on Amazon Linux)

25. Composer
• Dependency management
• Autoloader for project
• http://getcomposer.org

26. Installing via Composer
In your composer.json file:
{
"require":
{
"aws/aws-­‐sdk-­‐php":
"2.*"
}
}
On the command line.
php
composer.phar
install

27. Concepts in the SDK
• Commands
• Modeled Results
• Iterators
• Waiters
• Events & Plugins
• High-level Abstractions

28. Commands
• Encapsulates an operation to AWS
• Contains Request and Response objects
• Allows you set and get parameters
• Returns modeled results

29. Commands - Shorthand
$result
=
$s3-­‐>listObjects(array(
'Bucket'
=>
'my-­‐bucket-­‐name'
));
echo
$result['Objects'][0]['Key'];

30. $command
=
$s3-­‐>getCommand('ListObjects');
$command-­‐>set('Bucket',
'my-­‐bucket-­‐name');
$result
=
$command-­‐>getResult();
echo
$result['Contents'][0]['Key'];
$response
=
$command-­‐>getResponse();
echo
$response-­‐>getStatusCode();
echo
$response-­‐>getHeader('Content-­‐Length');
The Command Object

31. $c1
=
$s3-­‐>getCommand('PutObject',
array(
'Bucket'
=>
'my-­‐bucket-­‐name',
'Key'
=>
'my-­‐first-­‐key',
'Body'
=>
fopen('path/to/file1',
'r')
));
$c2
=
$s3-­‐>getCommand('PutObject',
array(
'Bucket'
=>
'my-­‐bucket-­‐name',
'Key'
=>
'my-­‐second-­‐key',
'Body'
=>
fopen('path/to/file2',
'r')
));
$s3-­‐>execute(array($c1,
$c2));
Parallel Commands

32. Modeled Results
• Array-like object
• Follows schema from service description
• Convenience methods like getPath()
$result
=
$s3-­‐>listBuckets();
$result['Buckets'][0]['Name'];
$result-­‐>get('Buckets');
$result-­‐>getPath('Buckets/0/Name');
$result-­‐>get('Buckets');
print_r($result-­‐>toArray());

33. Waiters
• Poll resources until available
• Handle asynchronous and eventually
consistent operations more easily
$s3-­‐>createBucket(array(
'Bucket'
=>
'my-­‐bucket'
));
$s3-­‐>waitUntilBucketExists(array(
'Bucket'
=>
'my-­‐bucket'
));

34. Iterators
• Iterate through entire result sets
• No handling of markers or tokens
• Uses SPL iterators and interfaces
$list
=
$s3-­‐>getIterator('ListObjects',
[
'Bucket'
=>
'my-­‐bucket'
]);
foreach
($list
as
$object)
{
echo
$object['Key']
.
PHP_EOL;
}

35. SDK 1.x – Before Iterators
$dynamo_db
=
new
AmazonDynamoDB();
$start_key
=
null;
$people
=
array();
do
{
$params
=
array(
'TableName'
=>
'people',
);
if
($start_key)
{
$params['ExclusiveStartKey']
=
array(
'HashKeyElement'
=>
array(
'S'
=>
$start_key
)
);
$start_key
=
null;
}
$response
=
$dynamo_db-­‐>scan($params);
if
($response-­‐>isOK())
{
foreach
($response-­‐>body-­‐>Items
as
$item)
{
echo

$item-­‐>name-­‐>S;

39. Events & Event Listeners
• Event slots in various parts of SDK
• Inject logic without extending classes
• Symfony2 Event Dispatcher
$s3-­‐>getEventDispatcher()
-­‐>addListener('<event>',
<fn>);

40. Plugins
• Implemented as event listeners
• Many built-in plugins from Guzzle
including easy wire logging
use
GuzzlePluginLogLogPlugin;
$s3-­‐>addSubscriber(
LogPlugin::getDebugPlugin()
);

41. Higher-level Abstractions
• S3 Multipart Uploader
• S3 Stream Wrapper
• DynamoDB Session Handler
• DynamoDB WriteRequestBatch
• SNS Message Validator
• Third-party Modules: ZF2, Silex, Laravel

42. $s3
=
$aws-­‐>get('S3');
$uploader
=
UploadBuilder::newInstance()
-­‐>setClient($s3)
-­‐>setSource('/path/to/large/file.mov')
-­‐>setBucket('my-­‐bucket')
-­‐>setKey('my-­‐object-­‐key')
-­‐>setConcurrency(3)
-­‐>build();
Multipart Uploader
