show_in_menu doesn't work with int value

[truongwp]

The show_in_menu parameter in register_post_type() function doesn't work with int value (or some other value which be treated as true if convert to boolean). I tried to use 1 instead of true, some other parameters work except show_in_menu. The problem is WordPress use Not Identical operator instead of Not Equal to check the value of show_in_menu when render admin menu items.

​According to the docs, show_in_menu only accepts bool or string. int values are not accepted and I can't see a reason of why they should be accepted.

If you can provide an use case on where switch to int could be valuable, maybe this could be reconsidered, but just asking to change for the sake of changing it its not a great idea.

I'm closing this as invalid. Feel free to reopen it, if you happen to have a use case to better showcase the need of this improvement
