[RFC] Renaming the stdClass to StdClass

[SerafimArts]

This PR proposes renaming stdClass to StdClass.

Reasons

If we consider the standard PHP API, the current stdClass is the only one that does not meet the class naming specifications... I can’t remember a single one that would recommend writing class names with a lowercase letter.

• Such a change name of stdClass to StdClass will improve the code base consistency.

Against

• PHP is case-insensitive in class naming, so the name new StdClass() inside any user's code can be used instead.
• This change that only superficially improves consistency, but affects backward compatibility.

BC

I assume that this change could break some codebase of tests that are based on the var_dump output or any other rather strange comparisons (like: get_class($obj) === 'stdClass').

Is this a potentially useful PR/RFC and does it make sense to test popular packages that will be affected?

[KalleZ]

I don't see the gain here in breaking backwards compatibility when you can already write:

$obj = new StdClass;

It is against the defined coding standards, but the gain versus the potential breakage here for just using a different set of capitalized letters is low to none here.

If you wish to make an RFC for it, then please go ahead and follow the wiki instructions.

I don't see the gain here in breaking backwards compatibility when you can already write:

Yes, I have already added this to the arguments "against". But I think this is a permissible change in major PHP 8

If you wish to make an RFC for it, then please go ahead and follow the wiki instructions.

I can’t take advantage of the existing registration process described in wiki 2.1 (https://wiki.php.net/rfc/howto), because I get an error message in response: "That wasn't the answer we were expecting".

That's why I decided to get the RFC here, along with the patch.

After looking at the wording on both the howto page and the registration, I agree it is a bit vague, but the answer you are looking for on the registration is found in the first section on the howto page

@KalleZ Well, you are really right. I really had to start with this.
