Answer 1

You have to add

  enctype="multipart/form-data"

in the form and leave action blank. After that, add following code

  if (isset($_POST['upload'])) {

 runMyFunction();
 }
 function runMyFunction(){
 $uploaded=$_FILES['photo']['name'];
 move_uploaded_file($_FILES['photo']['tmp_name'], $uploaded);
 list($width, $height) = getimagesize($uploaded);
 echo "width: " . $width . "<br />";
 echo "height: " .  $height;
 }
