Use self:: only when you don't have an actual instance handy, is a
general rule, I think...
self:: is kinda like using the Plato-like "ideal" of the class --
there's no actual instantiated real-world "thing" to work on.
You're working with an abstract non-existant idealized non-object.
$x (or $this) you are working with an actual real-life instantiated
"object".
Disclaimer:
This is how I thought of it in C++, rather than a ton of experience in
PHP...
PS
PHP 6 may become more "strict" about using / not using self:: where it
"should" be used... Depends on how the Internals 'discussions' pan
out...
