Images Rotating

I have a very strange problem.

On my website there is a file field that will allow the users to upload their profile picture.

It gets uploaded using JQuery and it gets saved using PHP .

If I upload from a PC / MAC / iPhone then there is no problem whatsoever, however if I upload using an Android device the image gets rotated.

The rotation is not even consistent, it could be 90% 180% or 270%, this happens when taking a image or selecting from the Gallery.

Why would this happen? and is there a possible fix?

This solved the issue

From the PHPDocs

<?php
$image = imagecreatefromstring(file_get_contents($_FILES['image_upload']['tmp_name']));
$exif = exif_read_data($_FILES['image_upload']['tmp_name']);
if(!empty($exif['Orientation'])) {
    switch($exif['Orientation']) {
        case 8:
            $image = imagerotate($image,90,0);
            break;
        case 3:
            $image = imagerotate($image,180,0);
            break;
        case 6:
            $image = imagerotate($image,-90,0);
            break;
    }
}
// $image now contains a resource with the image oriented correctly
?>
