Audience
This document is targeted at PHP developers writing packages for
submission into the PEAR repository. As any coding guidelines, it is
useful to developers using PHP in other environments. The requirements for
reading this text are only familiarity with PHP as a programming language,
as well as familiarity with the mechanism of Exceptions as an error
handling mechanism.
For those PHP developers unfamiliar with Exceptions, the wiki page
from which this document was extracted provides a good introduction, as
well as pointers to other references.
