The functions in this section do not fit neatly into any other section of the functional
reference. They are not available by default when compiling PHP, and most of them
require extra libraries. While none are essential to building PHP scripts, some are quite
useful in the right context. Because you may not be familiar with all the technologies in
this chapter, I've attempted to give a brief synopsis and links to Web sites where you can
learn more.

The list of extensions is growing rapidly. A few didn't make it into this edition of the
book for several reasons. Some are very specialized, and perhaps not of general interest.
Others are relatively immature, so I couldn't rely on them not to change. Most of them are
documented in the online manual, and people, myself included, are working on
documenting the others. It is likely that several new extensions will be created between
the time this text is finished and when they become available. The extensions that I know
exist and have chosen not to cover are: CyberCash, DAV, DOM, FDF, Hyperwave,
ICAP, MCAL, NIS, PDF, Readline, Recode.

Apache

The functions in this section are available only when PHP is compiled as a module for the
Apache Web server.
