Basic AWS S3 PHP setup

Question

I've been trying for a while to setup just a basic PHP implementation of an upload form to upload to Amazon's S3 service, but I can't get anything to work.

Reading through their docs, their examples all seem different. What is the correct way to provide credentials and upload a file?

On their github repo, it says:

// Require the Composer autoloader.
require 'vendor/autoload.php';

use Aws\S3\S3Client;

// Instantiate an Amazon S3 client.
$s3 = new S3Client([
    'version' => 'latest',
    'region'  => 'us-west-2'
]);

try {
    $s3->putObject([
        'Bucket' => 'my-bucket',
        'Key'    => 'my-object',
        'Body'   => fopen('/path/to/file', 'r'),
        'ACL'    => 'public-read',
    ]);
} catch (Aws\Exception\S3Exception $e) {
    echo "There was an error uploading the file.\n";
}

On http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html they say:

use Aws\S3\S3Client;

$client = S3Client::factory(array(
    'profile' => '<profile in your aws credentials file>'
));

// Upload an object by streaming the contents of a file
// $pathToFile should be absolute path to a file on disk
$result = $client->putObject(array(
    'Bucket'     => $bucket,
    'Key'        => 'data_from_file.txt',
    'SourceFile' => $pathToFile,
    'Metadata'   => array(
        'Foo' => 'abc',
        'Baz' => '123'
    )
));

// We can poll the object until it is accessible
$client->waitUntil('ObjectExists', array(
    'Bucket' => $this->bucket,
    'Key'    => 'data_from_file.txt'
));

Can anyone who has been able to do this recently shed some light on the setup here?

Answer 1

I ended up getting it working by just using the embeded credentials

<?php

date_default_timezone_set("America/Denver");

require "./aws/aws-autoloader.php";

use Aws\S3\S3Client;

$s3Client = S3Client::factory(array(
    'credentials' => array(
        'key'    => 'key',
        'secret' => 'secret',
    ),
    "region" => "us-east-1",
    "version" => "latest"
));

?>

Install Composer Once PHP CLI is installed, download the Composer installer script with:

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

Compile Composer with PHP Version

sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer

check composer composer

Install/download aws sdk library

composer require aws/aws-sdk-php

php -d memory_limit=-1 composer.phar require aws/aws-sdk-php

Sample Code Download File

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

use Aws\S3\S3Client;
$bucket ="sentimentanalysis2021";
$key ="KEY";
$secret ="SecretKEY";
$region ="ap-south-1";
$location = "/var/www/html/openpbx/record/temp/";
// Establish connection with DreamObjects with an S3 client.
$client = new Aws\S3\S3Client([
    'version'     => '2006-03-01',
    'region'      => $region,
    'endpoint'    => "https://s3.$region.amazonaws.com/",
        'credentials' => [
        'key'      => $key,
        'secret'   => $secret,
    ]
]); 
//var_dump($client);
//Download File
$file_s3 = null;
 $objects = $client->getPaginator('ListObjects', ['Bucket' => $bucket]);
    foreach ($objects as $listResponse) {
        $items = $listResponse->search("Contents[?ends_with(Key,'wav')]");
        foreach($items as $item) {
//            download($client,$item['Key'],$location);
        $client->getObject(array(
            'Bucket' => $bucket,
             'Key'    => $item['Key'],
                'SaveAs' => $location.$item['Key']
        ));
        $file_s3 =$location.$item['Key'];


        }
 }

//Read Files
$objects = $client->listObjectsV2([
        'Bucket' => $bucket,
]);
foreach ($objects['Contents'] as $object){
    echo "{$object['Key']}\t{$object['LastModified']}\n";
}

function download($client,$file,$location){
$client->getObject(array(
    'Bucket' => $bucket,
    'Key'    => $file,
    'SaveAs' => $location.$file
));
}

// Create Folder
 /* abc is the folder name */
$client->putObject(array( 
                   'Bucket' => $bucket,
                   'Key'    => "abc/",
                   'Body'   => "",
                   'ACL'    => 'public-read'
                  ));


$file_Path = '/amol/20220516141901_919033_9999.wav';
$key = basename($file_Path);
try{
    $result = $client->putObject([
        'Bucket'     => $bucket,
        'Key'        => $key,
        'SourceFile' => $file_Path,
        'ACL'        => 'private',
    ]);
} catch (S3Exception $e) {
    echo $e->getMessage() . "\n";
}
