Chris Jones has announced the release of the latest version of the Undergroupnd PHP & Oracle Manual.

A hot-off-the-press, free, 290 page, updated version of the Underground PHP & Oracle Manual is available for download from http://www.oracle.com/technology/tech/php/pdf/underground-php-oracle-manual.pdf. [...] The previous edition was released way back in May 2007. Since then, Oracle Database 11g and the OCI8 1.3 extension have been released, there have been various changes in PHP community, and I've simply just gathered more notes, examples and have more information to share.

The manual has doubled in size and includes tons of new content reflecting the updates since the previous release. Chris thanks those who helped in creating the content, helped get it out to the community and his co-author Alison Holloway.
