Unexpected exception when class wasn't loaded

[elicwhite]

So this is one of those cases where PHP is just plain weird / annoying.

In \Spot\Entity::fields($entityName) you have the check:

if(!is_subclass_of($entityName, '\Spot\Entity')) {
throw new \Spot\Exception($entityName . " must be subclass of '\Spot\Entity'.");
}

however, is_subclass_of() returns false if the class hasn't been loaded. I don't know if you care about this case, or how many different checks you'd have to add in all over the code to support it, but I just ran into this issue while trying to fix my autoloader's 5.3 support.

Interesting. Definitely not the expected behavior, although it kinda makes sense - PHP can't know the class structure or parents until the class is loaded/included because of it's shared-nothing nature. I could add an additional check to see if the class has been loaded, but like you said -- I'm not sure how many other places I would have to add the check also. I'll think about it and take a look at the existing code a bit.
