PHP图像上传到Amazon s3错误：无法显示，因为它包含错误

Question

I'm uploading an image from PHP to Amazon S3 servers.
It is stored successfully but I am not able to open the image ; I am getting this error:

The image “https://s3.amazonaws.com/buckename/24aaffa670e634a7da9a087bfa83abe6_400x400.png” cannot be displayed because it contains errors.

This is my code:

$sourcePath = $_FILES['filedata']['tmp_name'];

$actual_image_name='dinesh'.$_FILES['filedata']['name'];
$contentType= $_FILES['filedata']['type'];

S3::putObject($sourcePath,
              BUCKETNAME,
              baseName($actual_image_name),
              S3::ACL_PUBLIC_READ,array(),
              array('Content-Type' =>$contentType))
