Here is my composer.json which will identify the dependencies.
{
    "require": {
        "aws/aws-sdk-php": "3.0.6",
        "predis/predis": "1.0.1"  
    }
}

And command below will do the magic, something maven or ivy
>php composer.phar install

Some import classes will be as follow,
SQSConnector.inc

<?php
require 'vendor/autoload.php';

use Aws\Sqs\SqsClient;

class SQSConnector {
const queueURL = "https://sqs.us-east-1.amazonaws.com/xx_test";

protected $client = null;

function __construct(){
try {
$this->client = SqsClient::factory(array(
'region'  => 'us-east-1',
'version' => 'latest'
));
echo "Successfully connected to SQS\n";
} catch (Exception $e) {
    echo "Couldn't connected to SQS";
    echo $e->getMessage();
}
}
}

A time track class which can provide us more detail about the time consuming during the process, TimeTracker.inc
<?php

class TimeTracker implements Countable {

protected $count = 0;
protected $distribution;
protected $distributionPrecision = 0;
protected $startTime;
protected $totalTime;
protected $name;

public function __construct($name, $distributionPrecision = 2) {
$this->name = $name;
$this->distribution = array();
$this->distributionPrecision = $distributionPrecision;
$this->start();
}

public function count() {
return $this->count;
}

public function start($time = null) {
return $this->startTime = ($time === null) ? microtime(true) : $time;
}

public function stop($count = 1, $time = null) {
$interval = (($time === null) ? microtime(true) : $time) - $this->startTime;
$this->totalTime += $interval;
$key = (string)round($interval, $this->distributionPrecision);
if  (!array_key_exists($key, $this->distribution)) $this->distribution[$key] = 0;
$this->distribution[$key]++;
$this->count += $count;
return $interval;
}

public function __toString() {
ksort($this->distribution);
//return "{$this->name}: " . print_r($this->distribution, true) .
return "{$this->name}: {$this->count}m " . round($this->totalTime,2) . 's ' .
round($this->count/$this->totalTime,1) . "m/s\n";
}

}

Async Send the message via PHP in SQSSender.php
#!/usr/bin/php
<?php

require_once 'TimeTracker.inc';
require_once 'SQSConnector.inc';
use GuzzleHttp\Promise;

define('MSGNUM_REQUEST', 10);
define('MAXSIZE_REQUEST', 262144);

class SQSSender extends SQSConnector {
function sendMessage($job) {
$timer = new TimeTracker('sendMessage');
$promise_array = array();

if(strlen($job) >= MAXSIZE_REQUEST)
{
echo "The size of message is larger than 256KB\n";
var_dump($job);
return;
}

$promise = $this->client->sendMessageAsync(array(
'QueueUrl' => self::queueURL,
'MessageBody' => $job,
));
$promise->wait();
$timer->stop();

print $timer;
}

function sendMessageBatch($jobs, $timer) {
$promise_array = array();


$id=1;
$message = '';
$msg_num = 0;
foreach($jobs as $job)
{
$maxsize_msg = (int)(MAXSIZE_REQUEST/MSGNUM_REQUEST);
$tmp_msg = $message.$job;
if(strlen($job) >= $maxsize_msg)
{
$this->sendMessage($job);
}
else if(strlen($tmp_msg) >= $maxsize_msg)
{
$entries[] = array(
'Id' => $id,
'MessageBody' => $message
);
$id++;
$message = $job;
if($id > 10){
$promise = $this->client->sendMessageBatchAsync(array(
'QueueUrl' => self::queueURL,
'Entries' => $entries,
));
$entries = array();
$id = 1;

$promise_array['key' . count($timer)] = $promise;
/*if(count($promise_array) % 50 == 0){
Promise\unwrap($promise_array); //unwrap the promise list and wait for all promise complete
$promise_array = array();
}*/

$timer->stop($msg_num);
$msg_num = 0;
$timer->start();
}
$msg_num++;
}
else
{
$message = $tmp_msg;
$msg_num++;
}
}
$entries[] = array(
'Id' => $id,
'MessageBody' => $message
);
$promise = $this->client->sendMessageBatchAsync(array(
'QueueUrl' => self::queueURL,
'Entries' => $entries,
));
$promise_array['key' . count($timer)] = $promise;
Promise\unwrap($promise_array); //unwrap the promise list and wait for all promise complete
$promise_array = array();
$timer->stop($msg_num);
print $timer;
$timer->start();
}
}

/*$sender = new SQSSender;
$promise = $sender->send(500);
if(count($promise) > 0){
Promise\unwrap($promises);
}*/

?>

Before we run the test, the AMAZON require us to configure the key here>
carl-mac:.aws carl$ pwd
/Users/carl/.aws
carl-mac:.aws carl$ ls -l
total 8
-rw-r--r--  1 carl  staff  116 Jul  6 17:00 credentials
carl-mac:.aws carl$

The content will be as follow:
[default]
aws_access_key_id = xxxxxxxx
aws_secret_access_key = xxxxxxxxxxxxx
