Lukas Smith mentions today on his blog that, upon a little investigation into the workings of the RoundCube email client project, that they appear to be using a modified version of the PEAR::DB class.

While looking at the RoundCube source I stumbled over the use of PEAR::DB. True enough they had added their own wrapper around DB to work around its deficiencies. One of it was getting the last insert ID. Another one was the use of NOW() in their SQL commands.

He also mentions that he hacked the source up to help it use the MDB2 module he's been working on - it has some of the same functionality they were looking to PEAR::DB for, but had to hack around to get to work...
