   [default]
   AWSAccessKeyId=somekey
   AWSSecretKey=somesecretkey
   

2. I am doing following to use key and list all object

.

$s3 = new Aws\S3\S3Client([
    'version' => 'latest',
    'region'  => 'us-west-2'
]);


$result = $s3->listBuckets();
var_dump($result);

and i am getting error

According to the AWS PHP documentation, the format of the credentials file is as follows:

[default]
aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID
aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY

In your case, here is what I believe is happening:

1. first, the PHP library tries to get credentials from the environment, but they are not present so ...
2. next, it tries to get them from the INI file, but you have mis-spelled the keys so ...
3. finally, it tries to get them from the EC2 metadata server but it looks like you are not running on an EC2 instance so there is no metadata server and that attempt, using curl, times out.

You can see all of this clearly in the source code for the AWS PHP library.

The end result that bubbles up to you is that step #3 failed, but actually steps #1, #2, and #3 failed. So, I think the fix is as simple as correcting the key names in the INI file.
