如果对象为0，如何检查对象是否为空

Question

$view = new UserView();
var_dump(is_null($view))
echo '<br>';
var_dump($view);

bool(false)

object(UserView)#2 (0) { }

How is this even possible? And how I check if the object is not null?

Answer 1

Your object is not null, it's just empty, try :

 $empty = (bool) count((array) $view);
