16 Miscellaneous topicsThis is NOT the latest copy of this book; click here for the latest version.
I have to admit that I hate the idea of a "miscellaneous" chapter as much as the next person - surely all parts of PHP fit nicely together into groups of associated functionality? Well, no - although the majority of this book is split up nicely into related sections, there are several parts that simply do not relate to anything else close by or deserve their own section to give them justice.
