use Aws\S3\S3Client;

$awsAccessKey = 'XXXX';
$awsSecretKey = 'YYYYYYYYYY';
$bucket = 'your-bucket-name';

// File to be upload
$filename = 'sample.txt';

// Instantiate an Amazon S3 client.
$s3Client = new S3Client([
    'version' => 'latest',
    'region'  => 'us-east-1', // Your AWS region
    'credentials' => [
        'key'    => $awsAccessKey,
        'secret' => $awsSecretKey
    ]
]);

// file to upload, file path
$file_Path = __DIR__ . $filename;

$key = basename($file_Path);

try {
    $result = $s3Client->putObject([
        'Bucket' => $bucket,
        'Key'    => $key,
        'Body'   => fopen($file_Path, 'r'),
        'ACL'    => 'public-read',
    ]);

    echo "<pre>";
    print_r($result);

} catch (Aws\S3\Exception\S3Exception $e) {
