AWS SQSをSDK ver1を使ってPHPから実行するサンプル

<?php
require_once ('Vendor/aws_sdk/sdk.class.php');

$sqs = new AmazonSQS();
$region = AmazonSQS::REGION_APAC_NE1;
$sqs->set_region($region);
$queueName = 'キュー名';
$queueURL = $sqs->create_queue($queueName)->body->CreateQueueResult->QueueUrl;
$data = $sqs->send_message($queueURL, '値' . time());
if ($data->isOK()) {
    echo 'OK';
}
