How to access the property of an object if it has a similar name?

Question

PHP

I unload posts through the API, then I do json_decode, at the output I get a mess of StdObjects and arrays, one of the object properties has the name 'wp:featuredmedia', which contradicts the rule for naming variables (array elements and object properties)

Then how to access it?

Answer 1

$obj->{"some strange name"} methods also work
