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

Simple. Just check the width and height and compare them to get orientation. Then resize accordingly. Straight-forward really. If you are trying to maintain aspect ratio, but fit into some square box you could use something like this:

public static function fit_box($box = 200, $x = 100, $y = 100)
{
  $scale = min($box / $x, $box / $y, 1);
  return array(round($x * $scale, 0), round($y * $scale, 0));
}
