use Aws\S3\S3Client;
public function aws_upload(){
require 'vendor/autoload.php';
if(isset($_FILES["left_front"]) && $_FILES["left_front"]["error"] == 0){
$allowed = array("jpg" => "image/jpg", "jpeg" => "image/jpeg", "gif" => "image/gif", "png" => "image/png");
$filename = $_FILES["left_front"]["name"];
$filetype = $_FILES["left_front"]["type"];
$filesize = $_FILES["left_front"]["size"];
}
// Instantiate an Amazon S3 client.
$s3 = new S3Client([
'version' => 'latest',
'region' => AWS_REGION,
'credentials' => [
'key' => ACCESS_KEY_ID,
'secret' => SECRET_ACCESS_KEY
]
]);
$bucketName = 'demokrishna';
$key = basename($filename);
try {
$result = $s3->putObject([
'Bucket' => $bucketName,
'Key' => $key,
'acl' => 'public-read'
// 'ACL' => 'public-read',
]);
echo $result->get('ObjectURL');
} catch (Aws\S3\Exception\S3Exception $e) {
echo "There was an error uploading the file.\n";
echo $e->getMessage();
}
}

Answer 1

You have supplied bucket, key, and ACL but you have not supplied the file contents. You can do this using either a Body or a SourceFile.
Example with Body:
$result = $s3Client->putObject([
'Bucket' => $bucket,
'Key' => $key,
'Body' => 'Hello world!',
'ACL' => 'public-read'
]);
Example with SourceFile:
$file_Path = 'folder/filename.jpg';
$result = $s3Client->putObject([
'Bucket' => $bucket,
'Key' => $key,
'SourceFile' => $file_Path,
'ACL' => 'public-read'
]);
Also, note that it's 'ACL', not 'acl'. Please read the putObject documentation.

Answer 2

$key_bucket = basename($filename);
$result = $s3->putObject([
'Bucket' => $bucketName, // bucketname
'Key' => $key_bucket,
'StorageClass' => 'REDUCED_REDUNDANCY',
'SourceFile' => $value['tmp_name'] //temporary path
]);
It works for me
