Laravel file upload s3 Multipart - laravel

Question

how do I integrate the multipart upload of s3? I am uploading to s3 and everything works. just I want to refactor the code to S3 multipart upload because the files are too large on the server
// Amazon checking folder
$directory = 'Case/'. $caseDir;
foreach ($request->file('fileslab') as $s3file) {
// Getting request names & extension
$s3patientFirstName = $request->patient_firstname;
$s3patientLastName = $request->patient_lastname;
$s3SavedOrigName = $s3file->getClientOriginalName();
$SendFileToS3 = $s3patientFirstName . '_' . $s3patientLastName . '_' . time() . $s3SavedOrigName;
$contents = file_get_contents($dbfile->getRealPath());
$path = Storage::disk('s3')->put($directory. '/' .$SendFileToS3, $contents);
if (!Storage::disk('s3')->exists($directory)){
Storage::disk('s3')->makeDirectory($directory);
$path = Storage::disk('s3')->put( $directory. '/' . $SendFileToS3, $contents );
}else{
$path = Storage::disk('s3')->put( $directory. '/' .$SendFileToS3, $contents);
}
The Amazon SK Example is below:
require 'vendor/autoload.php';
use Aws\Common\Exception\MultipartUploadException;
use Aws\S3\MultipartUploader;
use Aws\S3\S3Client;
$bucket = '*** Your Bucket Name ***';
$keyname = '*** Your Object Key ***';
$s3 = new S3Client([
'version' => 'latest',
'region' => 'us-east-1'
]);
// Prepare the upload parameters.
$uploader = new MultipartUploader($s3, '/path/to/large/file.zip', [
'bucket' => $bucket,
'key' => $keyname
]);
// Perform the upload.
try {
$result = $uploader->upload();
echo "Upload complete: {$result['ObjectURL']}" . PHP_EOL;
} catch (MultipartUploadException $e) {
echo $e->getMessage() . PHP_EOL;
}

I fixed it.
foreach ($request->file('fileslab') as $s3file) {
$directory = 'Case/'. $caseDir;
$contents = fopen($s3file, 'rb');
$s3patientFirstName = $request->patient_firstname;
$s3patientLastName = $request->patient_lastname;
$s3SavedOrigName = $s3file->getClientOriginalName();
$SendFileToS3 = $s3patientFirstName . '_' . $s3patientLastName .
'_' . time() . $s3SavedOrigName;
$disk = Storage::disk('s3');
$s3 = new S3Client([
'version' => 'latest',
'region' => 'us-west-1'
]);
$uploader = new MultipartUploader($s3, $contents, [
'bucket' => $_ENV['AWS_BUCKET'],
'key' => $SendFileToS3,
]);
try {
$result = $uploader->upload();
} catch (MultipartUploadException $e) {
return $e->getMessage();
}
}
