php-awsHow can I use the PHP AWS S3 S3Client to upload files?

The AWS S3Client in PHP can be used to upload files to an Amazon S3 bucket. The following example code can be used to upload a file:

<?php
$s3Client = new Aws\S3\S3Client([
    'region'  => 'us-west-2',
    'version' => 'latest',
    'credentials' => [
        'key'    => 'YOUR_AWS_ACCESS_KEY_ID',
        'secret' => 'YOUR_AWS_SECRET_ACCESS_KEY',
    ]
]);

$result = $s3Client->putObject([
    'Bucket' => 'my-bucket',
    'Key'    => 'my-file.txt',
    'Body'   => 'this is the body!'
]);

echo $result['ObjectURL'];
?>

The code above will upload a file named my-file.txt to the bucket my-bucket with the body this is the body!. The $s3Client variable is an instance of the S3Client class. The putObject method is used to upload the file, and the ObjectURL of the uploaded file is returned in the $result variable.
