How to generate sequential GUIDs?

Are there PHP l开发者_运维知识库ibraries to generate sequential GUIDs for usage in a MySQL database?

If you mean uuids based on a common prefix, such as MAC and time, have a look at uniqid. Here you can also find some code for RFC 4211 compliant UUIDS. If you want to be on the safe side, use this wrapper to libuuid: pecl uuid. Haven't tested it though, YMMV.

I believe what is being asked for is, does MySQL have support for Sequential Id's the way that SQL Server does?

Now before everyone asks why use GUIDS, GUIDS will allow one to move/merge data between tables and databases.
