Help in finding and downloading Amazon S3 SDK version 2

Hello,
i want to upload a file, download a file and delete a file in the Amazon S3.
My PHP version, on my Linux centos server is 5.3.3.
i read that i can't use the SDK version 3 , because its minimum requirements (5.5)

Been looking for two days, for a page to download the version 2.7.27, which does, support php 5.3.3.
found this but no download option:
https://packagist.org/packages/aws/aws-sdk-php#2.7.27

Where can i download the old SDK that support PHP 5.3.3 ?
and if i can't, where can i find a link that explains, how to write PHP code that operates Amazon S3 commands without the SDK.
can't find it anywhere sorry...

thank you!
