Some API Results are lists of items, like the result of CloudFormationClient::DescribeStacks(). These results implement \IteratorAggregate and will automatically use AWS's pagination API to make a new request to fetch the remaining resources in the list.

use AsyncAws\CloudFormation\CloudFormationClient; $cloudFormation = new CloudFormationClient(); $result = $cloudFormation->describeStacks(); foreach($result as $stack) { echo $stack->getStackName(); }

These results also provide methods to fetch metadata returned by AWS or to explicitly access the list of items by using a meaningful method name.

-foreach($result as $stack) {
+foreach($result->getStacks() as $stack) {

If you want to disable pagination, you may call the getStacks() function with boolean true as first argument.

-foreach($result->getStacks() as $stack) {
+foreach($result->getStacks(true) as $stack) {

Some endpoints return several lists of items in the same response, like the result of S3::ListObjectsV2(). When iterating over those results, all lists will be mixed in the yielded items.

use AsyncAws\S3\Input\ListObjectsV2Request; use AsyncAws\S3\S3Client; use AsyncAws\S3\ValueObject\AwsObject; $s3 = new S3Client(); $objects = $s3->listObjectsV2(new ListObjectsV2Request([ 'Bucket' => 'my-company-website', 'Delimiter' => '/' ])); foreach($objects as $object) { if ($object instanceof AwsObject) { echo '- '.$object->getKey(); } else { echo 'd '.$object->getPrefix(); } }
