PHP remove orientation exif from image only (without using imagick)

I wrote a script that batch resizes uploaded images locally and creates thumbnails. The problem is if some images are oriented vertically but after resizing they rotate horizontally. This is due to the exif orientation of the image. Is there an easy way to remove orientation exif from an image via PHP? I know Imagick can be done, but I can't/don't want to install it.
