HTTP 103 Early Hint is described in RFC8297, see also for explanations.

PHP cannot generate such hints, while it would be useful in practice.

Could a function be added to send them?

send_early_hints($headers); or similar

The 103 Early Hints RFC is still experimental.

If you'd like built-in support for this then you should bring up the subject on the internals mailing list, given that it goes beyond the bounds of the simple header management tools that PHP currently provides.

But this sounds like something that will need web server support first, and some cursory searches don't show that to be the case yet.
