Hello Everyone,
I am using amazon s3 bucket in a site. And in the amazon SDK for PHP given here, is not running the samples after changing the values in config file(config-sample.inc.php). And as per the instruction, i tried to view this page after set the values of key and secret values. _samples/cli-s3_get_urls_for_uploads.php which is showing the error as follows.

Any help regarding this to solve the issue would be greatly appreciated.
