One level of indentation per method.
Don't use the ELSE keyword.
Wrap all primitives and Strings in classes.

No classes with more than two instance variables.

PHP Style Guide

All rules and guidelines in this document apply to PHP files unless otherwise noted. References to PHP/HTML files can be interpreted as files that primarily contain HTML, but use PHP for templating purposes.

The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

Most sections are broken up into two parts:

Some categories: Geographical (countries, cities, parks, rivers, lakes, streets), entertainment (flintsones, simpsons, disney films, celebrities), companies (hotels, airports, local shops, restarants), astronomy (planets, comets, space missions), literature (mythology, philosophers, writers of particular generes, languages), political (presidents, judges, congressmen, terminology), science (units of measure, anatomy, instruments, scientists), industry (tools, machines, inventions, inventors), computers (terminology, programming languages, number systems).

	Some hostnames I've seen, used, or expect to use..
