Which SDK should I use?

PHP developers will find both versions of the AWS SDK for PHP natural and easy to use.

Since both SDKs work well side-by-side in the same application,

a developer can continue to rely on the initial AWS SDK for PHP when:

It requires access to AWS services not yet supported by AWS SDK for PHP 2,

Porting would require significant effort.

We will continue to broaden support for AWS services in the AWS SDK for PHP 2.

Additionally, a developer may take a staged approach to gradually move parts of their application to the new SDK.

PHP developers should begin planning how to take full advantage of all that the AWS SDK for PHP 2 offers.
