Does anyone know all the possible results for the 3rd value returned from PHP's getimagesize() function?
Example this code below will return
$imageinfo['2'] = 2; for a jpg image $imageinfo['2'] = 3; for a png image $imageinfo['2'] = 0; for a gif image
the numbers might not be correct above but you get the idea.
I can not find on php.net or anywhere else a list of all possible results for the 3rd value
$imageinfo = getimagesize($imageurl);
$image_type = $imageinfo['2'];
