Upload a File in Multiple Parts Using the PHP SDK Low-Level API
This topic guides shows how to use the low-level uploadPart method from version 3 of the AWS SDK for PHP to upload a file in multiple parts. It assumes that you are already following the instructions for Using the AWS SDK for PHP and Running PHP Examples and have the AWS SDK for PHP properly installed.
The following PHP example uploads a file to an Amazon S3 bucket using the low-level PHP API multipart upload. For information about running the PHP examples in this guide, see Running PHP Examples.
require 'vendor/autoload.php';
use Aws\S3\S3Client;
$bucket = '*** Your Bucket Name ***';
$keyname = '*** Your Object Key ***';
$filename = '*** Path to and Name of the File to Upload ***';
$s3 = new S3Client([
'version' => 'latest',
'region' => 'us-east-1'
]);
$result = $s3->createMultipartUpload([
'Bucket' => $bucket,
'Key' => $keyname,
'StorageClass' => 'REDUCED_REDUNDANCY',
'ACL' => 'public-read',
'Metadata' => [
'param1' => 'value 1',
'param2' => 'value 2',
'param3' => 'value 3'
]
]);
$uploadId = $result['UploadId'];
// Upload the file in parts.
try {
$file = fopen($filename, 'r');
$partNumber = 1;
while (!feof($file)) {
$result = $s3->uploadPart([
'Bucket' => $bucket,
'Key' => $keyname,
'UploadId' => $uploadId,
'PartNumber' => $partNumber,
'Body' => fread($file, 5 * 1024 * 1024),
]);
$parts['Parts'][$partNumber] = [
'PartNumber' => $partNumber,
'ETag' => $result['ETag'],
];
$partNumber++;
echo "Uploading part {$partNumber} of {$filename}." . PHP_EOL;
}
fclose($file);
} catch (S3Exception $e) {
$result = $s3->abortMultipartUpload([
'Bucket' => $bucket,
'Key' => $keyname,
'UploadId' => $uploadId
]);
echo "Upload of {$filename} failed." . PHP_EOL;
}
// Complete the multipart upload.
$result = $s3->completeMultipartUpload([
'Bucket' => $bucket,
'Key' => $keyname,
'UploadId' => $uploadId,
'MultipartUpload' => $parts,
]);
$url = $result['Location'];
echo "Uploaded {$filename} to {$url}." . PHP_EOL;
