Retrieve image orientation in PHP

Question

How can I get the image orientation (landscape or portrait) of an image (JPEG or PNG) in PHP?

I created a php site where users can upload pictures. Before I scale them

Answer 1

I've always done this:

list($width, $height) = getimagesize('image.jpg');
if ($width > $height) {
    // Landscape
} else {
    // Portrait or Square
}
