Changeset 34034 for trunk/src/wp-admin/includes/ms.php

Message:

Require numeric IDs in user deletion functions.

wp_delete_user() and wpmu_delete_user() both require an $id parameter.
Previously, the functions did not verify that the value passed was, in fact,
a number. As such, passing an object or any other entity that would be cast
to int 1 would result in user 1 being deleted. We fix this by enforcing
the requirement that $id be numeric.

Props dipesh.kakadiya, utkarshpatel, juliobox.
Fixes #33800.
