As you should have a fixed parameter order in your function you don't need
to pass the variable names in. So this is OK for up to three or four params:
doStuff('value1', 'value2', 'value3', 'value4');
If your function takes more than four parameters an associative array would
be the way to go (your first example). You might consider splitting it up
into several functions if it takes that many arguments.
