You can do this as such

$filename = $_FILES['image']['tmp_name'];
$size = getimagesize($filename);

// or

list($width, $height) = getimagesize($filename);
// USAGE:  echo $width; echo $height;

Using the condition combined, here is an example

if (isset($_FILES['image'])) {
    $filename = $_FILES['image']['tmp_name'];
    list($width, $height) = getimagesize($filename);
    echo $width; 
    echo $height;    
}
