amazon multipart upload PHP sdk version 2 - php

Question

I tried to upload large file into Amazon s3 using PHP. I have found nice solutions on various forums but these solutions are for SDK version 1 .
http://docs.aws.amazon.com/AmazonS3/latest/dev/LLuploadFilePHP.html
Of course, I have found examples on Amazon API documentation. This example expects file on local disk and can not handle with input stream.
I couldn't find similar examples for the SDK for PHPv2 as shown in first link.
Did someone solved similar problem successfully?

Answer 1

I recently just prepared a code sample for this. In this example I am using a file, but you can use a stream as well.
use Aws\S3\S3Client;
use Aws\Common\Enum\Size;
// Instantiate the client.
$s3 = S3Client::factory(array(
'key' => '*** your-aws-access-key-id ***',
'secret' => '*** your-aws-secret-key ***'
));
$file = fopen($filename, 'r');
// 1. Create a new multipart upload and get the upload ID.
$response = $s3->createMultipartUpload(array(
'Bucket' => $bucket,
'Key' => $keyname
);
$uploadId = $result['UploadId'];
// 2. Upload the data in parts.
$parts = array();
$partNumber = 1;
while (!feof($file)) {
$result = $s3->uploadPart(array(
'Bucket' => $bucket,
'Key' => $key,
'UploadId' => $uploadId,
'PartNumber' => $partNumber,
'Body' => fread($file, 5 * Size::MB),
));
$parts[] = array(
'PartNumber' => $partNumber++,
'ETag' => $result['ETag'],
);
}
// 3. Complete multipart upload.
$result = $s3->completeMultipartUpload(array(
'Bucket' => $bucket,
'Key' => $key,
'UploadId' => $uploadId,
'Parts' => $parts,
));
$url = $result['Location'];
fclose($file);
