Deleting One Object (Non-Versioned Bucket)

1. Create instance of S3 client using Aws\S3\S3Client class factory().

   $s3 = S3Client::factory();

2. Execute the Aws\S3\S3Client::deleteObject() method with bucket name and a key name.

   $result = $s3->deleteObject(array( 'Bucket' => $bucket, 'Key' => $keyname ));

If versioning is enabled DELETE MARKER Will be added. (Reference)

EXAMPLE

require 'vendor/autoload.php';
use Aws\S3\S3Client;
$s3 = S3Client::factory();

$bucket = '*** Your Bucket Name ***';
$keyname = '*** Your Object Key ***';

$result = $s3->deleteObject(array(
    'Bucket' => $bucket,
    'Key'    => $keyname
));

More Reference can be found here.

You can use deleteObject() method, refer the doc.

use Aws\S3\S3Client;

$s3 = S3Client::factory();

$bucket = '*** Your Bucket Name ***';
$keyname = '*** Your Object Key ***';

$result = $s3->deleteObject(array(
    'Bucket' => $bucket,
    'Key'    => $keyname
));

You can use the aws s3 delete API method which delete the uploaded file. you can achieve it like below.

use Aws\S3\S3Client;

$s3 = new S3(awsAccessKey, awsSecretKey);

$s3->deleteObject("bucketname", filename);
