S3 Image upload after GD resize PHP - php

Question

I have working code that uploads an image to Amazon S3
Working code...
$filename = $s."/avatars/".$user_id."-".$file['name'];
$path_parts = pathinfo($file['name']);
$ext = $path_parts['extension'];
$input_file = S3::inputFile($file['tmp_name'], false);
if(S3::putObject($input_file, 'mybucket', $filename, S3::ACL_PUBLIC_READ)){
//Success handling
} else {
// Error handling
}
However, when I use GD to resize it, and try to upload it fails to work anymore.
Unworking code...
$size = getimagesize($file['tmp_name']);
$x = (int) $input['x'];
$y = (int) $input['y'];
$w = (int) $input['w'] ? $input['w'] : $size[0];
$h = (int) $input['h'] ? $input['h'] : $size[1];
$data = file_get_contents($file['tmp_name']);
$vImg = imagecreatefromstring($data);
$dstImg = imagecreatetruecolor($nw, $nh);
imagecopyresampled($dstImg, $vImg, 0, 0, $x, $y, $nw, $nh, $w, $h);
ob_start();
imagejpeg($dstImg, null, 100);
$jpeg = ob_get_contents();
ob_end_clean();
//Send to S3
$input = S3::inputFile($jpeg, false);
if(S3::putObject($input, 'mybucket', $filename, S3::ACL_PUBLIC_READ)){
// Success handling
} else {
// Error handling
}
Error message I receive is...
S3::inputFile(): Unable to open input file: ÿØÿà
Any ideas?? Am I getting the stream incorrectly?? Am I supposed to do something differently after resizing?? Do I even have to read the stream?? Or can I send the $dstImg resource??
Any help would be greatly appreciated

For anyone else having this problem.
I solved it like this
Changed this...
ob_start();
imagejpeg($dstImg, null, 100);
$jpeg_to_upload = ob_get_contents();
ob_end_clean();
To this...
$jpeg_to_upload = tempnam(sys_get_temp_dir(), "tempfilename");
imagejpeg($dstImg, $jpeg_to_upload);
Then sent it...
$input = S3::inputFile($jpeg_to_upload, false);
if(S3::putObject($input, 'mybucket', $filename, S3::ACL_PUBLIC_READ)){
