If you’re working with CodeIgniter, using Amazon S3 just got even easier!

To set up the library, open it up in your text editor and enter your key and secret key at the top of the library.

// -----------------------------------------
// -----------------------------------------
// your API key ID
var $keyId = "";
// your API Secret Key
var $secretKey = "";
// -----------------------------------------
// -----------------------------------------

Here’s an example of how to use the library in your controller:

$contents = file_get_contents($path);
$this->load->library('s3');
$this->s3->putObject($filename $contents, $bucketName, 'private', $file['type']);
