There's absolutely no "code style" enforced from what I've seen. Granted LastPost v2 is going to be my first module for xoops, it's also the very first serious work I've done in PHP. I'm using a strict code style that I'm already familiar with from other projects. For example:
String strName = "string of text";
char = 'a';
for (int i = 0; i < strName.length(); i++) {
...;
} // Notes of "for loop"
It's the default code style found in Java, but I take it to a further extreme--putting spaces between operators, notes always at the end of a loop, whitespace after deliminators (ie ';'), and /** block commenting complete with @params */. It's something I learned about four or five years back working with Roj in ARexx. If you can't lock down a code style, half the work will be sloppy as all hell.
