PHP：与字符串表示的类名相同的instanceof

Question

It's best to explain by an example. I look for a function "theFunctionILookFor" that will make the code work.

$myClassName = "someName";
$parentOrInterfaceName = "someParent";
if ( theFunctionILookFor ($myClassName))  echo "is parrent";

edit: I try to avoid instantiating the class just to perform this check. I would like to be able to pass 2 string parameters to the checking function

Answer 1

Looks like this is my answer: is_subclass_of

It can accept both parameters as strings
