There are a few small glitches with php 4.2 that are being worked out. The next release which is php 4.2.1 is due out on Apr 26 [Friday]. This release will hopefully contain a fix for connecting to a local database using "localhost" as the hostname. The php mailing list mentions bugs with Apache 2.0 as well. Visit mailing lists for updates, and wait till Friday to grab the latest release.

With kind regards,
