php-awsHow do I use AWS SNS to publish a message using PHP?

To use AWS SNS to publish a message using PHP, you must first install the AWS SDK for PHP. You can then use the following code to publish a message:

<?php
// Include the SDK using the Composer autoloader
require 'vendor/autoload.php';

// Create an SNS client
$sns = new Aws\Sns\SnsClient([
    'region'  => 'us-east-1',
    'version' => 'latest'
]);

// Publish a message to an SNS topic
$result = $sns->publish([
    'Message' => 'Hello world!',
    'TopicArn' => 'arn:aws:sns:us-east-1:123456789012:MyTopic',
]);

echo $result['MessageId'];

This code will produce an output of the MessageId of the published message.
