Image rotation: PNG or JPEG depend on file type with save on your server

// File and rotation
$rotateFilename = '/var/www/your_image.image_type'; // PATH
$degrees = 90;
$fileType = strtolower(substr('your_image.image_type', strrpos('your_image.image_type', '.') + 1));

if($fileType == 'png'){
   header('Content-type: image/png');
   $source = imagecreatefrompng($rotateFilename);
   $bgColor = imagecolorallocatealpha($source, 255, 255, 255, 127);
   // Rotate
   $rotate = imagerotate($source, $degrees, $bgColor);
   imagesavealpha($rotate, true);
   imagepng($rotate,$rotateFilename);

}

if($fileType == 'jpg' || $fileType == 'jpeg'){
   header('Content-type: image/jpeg');
   $source = imagecreatefromjpeg($rotateFilename);
   // Rotate
   $rotate = imagerotate($source, $degrees, 0);
   imagejpeg($rotate,$rotateFilename);
}

// Free the memory
imagedestroy($source);
imagedestroy($rotate);

It's works for me, try it.
