PHP：如何使用存储在成员字符串中的名称制作类的新对象？

Question

So I want to do something like this:

$ob = new $this->other_class_name;

but it fails. How can I do it without storing other_class_name in local variable?

Answer 1

Save the name in another variable:

$class = $this->other_class_name;
$ob = new $class;

Answer 2

Try this:

$class = get_class($this->other_class_name);
$ob = new $class;
