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

list($width, $height) = getimagesize("path/to/your/image.jpg");

if( $width > $height)
    $orientation = "landscape";
else
    $orientation = "portrait";
