So far, we have complete the download and installation process for AWS SDK for PHP. Now, we will discuss the process about creating the client.

Creating a client:

First, we will create a client object. We will use one of the following techniques.

  1. Factory method
  2. Listing your buckets
  3. Listing objects in your buckets
  4. Uploading a file
  5. Uploading objects
  6. Listing objects in your buckets
  7. Downloading objects
  8. Saving objects to a file
  9. Cleaning up

Factory Method

This is easiest way among all the methods which help us to run the quickly and efficiently. So, we will use the Aws\S3\S3Client::factory()method and by using profile option, we will provide our credentials.

Here, we can give our credential profile, specify the access keys directly i.e (via key and secret).

Listing your buckets

A method listBuckets is used to list our all the buckets owned by our account.

An object Guzzle\Service\Resource\Model is returned if we use the AWS SDK for PHP return . This object will have all of the data returned from this service. This object willl also contain a get() method. This method is used to retrieve the values from the model by name. Moreover, the rested vlaues will be retrieve using getPath() method.

Listing objects in your buckets

This method is a lost of an easier way to list the objects in buckets. Because new SDK with iterators helps us. For this, we will use ListObjectsIterator.

This iterator (ListObjects) also works with other parameters.
