Using S3 client directly in Laravel

s3-in-laravel.php

<?php

/** @var \Illuminate\Filesystem\FilesystemAdapter $fs */
$fs = \Storage::disk('object_storage');

/** @var \League\Flysystem\Filesystem $driver */
$driver = $fs->getDriver();

/** @var \League\Flysystem\AwsS3v3\AwsS3Adapter $adapter */
$adapter = $driver->getAdapter();

/** @var \Aws\S3\S3Client $client */
$client = $adapter->getClient();

// upload
$source = fopen("/source/file.typ", "r");
try {
    $client->putObject([
        'Bucket' => 'name-of-the-app',
        'Key'    => 'destination/path',
        'Body'   => $source,
    ]);
} catch (\Aws\S3\Exception\S3Exception $e) {
    // handle exception
} finally {
    fclose($source);
}

Thanks !
You can even have the bucket with $adapter->getBucket()

FYI this no longer works with Laravel 9.x

what works now for getting the bucket name programmatically?

@DustinCai Why do you need the bucket name programmatically? You don't have it through some other variable or config that you used to setup the S3 disk connection?
