Well, let's sort out what sorts of errors we're dealing with under E_STRICT, 
and then see what the options are.  In general I'd suggest going with the 
most pretty-code-friendly solution in most cases, unless there's a dramatic 
speed difference.  

- I don't believe there's any classes in Drupal, so var vs. public/private is 
a non-issue.

- Checking for variable existence.  isset() is the standard way I know of, 
baring just always initializing a variable.  The latter is not always 
possible, though.  Does PHP have a cleaner default value syntax than the 
ternary operator?  It works, but it's ugly. :-)  (Python, I believe, can do   
x = y || z to use z as a default value if y is not set.  I don't know if PHP 
has an equivalent.)

- NULL values.  Where would these be an issue other than pulling data from the 
database?  I'm of the mind that given MySQL's poor handling of null vs. 
default values, we should just always specify NOT NULL and a default for 
every field, period.  That default value is then understood to be the "no 
value" flag.  

Other thoughts?

which an individual may exclusively possess as long as he keeps it to 
himself; but the moment it is divulged, it forces itself into the possession 
of every one, and the receiver cannot dispossess himself of it."  -- Thomas
