Managing Visibility Timeout in Amazon SQS

A visibility timeout is a period of time during which Amazon SQS prevents other consuming components from receiving and processing a message. To learn more, see Visibility Timeout.

The example below shows how to:

• Change the visibility timeout of specified messages in a queue to new values, using ChangeMessageVisibilityBatch.

All the example code for the AWS SDK for PHP is available here on GitHub.

Credentials

Before running the example code, configure your AWS credentials, as described in Credentials.

Change the Visibility Timeout of Multiple Messages

require 'vendor/autoload.php';
use Aws\Sqs\SqsClient;
use Aws\Exception\AwsException;

$queueUrl = "QUEUE_URL";
$client = new SqsClient([
    'profile' => 'default',
    'region' => 'us-west-2',
    'version' => '2012-11-05'
]);
try {
    $result = $client->receiveMessage(array(
        'AttributeNames' => ['SentTimestamp'],
        'MaxNumberOfMessages' => 10,
        'MessageAttributeNames' => ['All'],
        'QueueUrl' => $queueUrl, // REQUIRED
    ));
    $messages = $result->get('Messages');
    if ($messages != null) {
        $entries = array();
        for ($i = 0; $i < count($messages); $i++) {
            array_push($entries, [
                'Id' => 'unique_is_msg' . $i, // REQUIRED
                'ReceiptHandle' => $messages[$i]['ReceiptHandle'], // REQUIRED
                'VisibilityTimeout' => 36000
            ]);
        }
        $result = $client->changeMessageVisibilityBatch([
            'Entries' => $entries,
            'QueueUrl' => $queueUrl
        ]);
        var_dump($result);
    } else {
        echo "No messages in queue \n";
    }
} catch (AwsException $e) {
    // output error message if fails
    error_log($e->getMessage());
}
