As posted over on the Zend Developer Zone, Marc Gear has posted a new review over on his blog of the guide that php|architect magazine has created to help prepare developers for Zend's PHP 5 Certification.
I brought the book to make sure that my knowledge was sufficient to take the test [...] however, having read most of the book last night, I think it would be a good addition to my bookshelf, especially to lend to other developers on my team.
He briefly covers the topics in the book (including basics, functions, stream, security, etc) and a general impression of how the book presented them overall. His opinion of the resource is definitely a good one, summed up well by the above comments.
His only complaint was a small one (and not even about the content of the book) - that the spine was printed upside down so it looks a bit odd on the shelf.
