> Many of the PHP extensions are direct exposure to underlying libraries. MySQL introduced a 'real escape string' in their client library, PHP exposed that directly.

Don't most ecosystems use some type of namespace for that instead of exposing everything as global functions? Those practices were quite late to the PHP community.
