Over on Micheal Kimsal's weblog this morning, he provides a bit of his own take on the whole MySQL license change PHP went through a while back.

In effect what the MySQL license change had initially done was restricted the ability for PHP to distribute the MySQL client libraries which has been the case for some time. The problem with distributing the libraries *can* be that the version of the server you're connecting to is out of sync with the client libraries. Not usually a big issue, but it can cause problems.

Instead, SQLite has been pushed as the "next big thing", but Michael doesn't quite see it that way, describing it as: an alternative technology that is certainly not as tested, widely used, debugged or trusted as MySQL.
