I almost certain that the above to equate to the exact same OPCODEs when
the php is compiled ... and you will never be able to benchmark a valid difference
between them either way.

the brackets are superfluous - but not incorrect.
newcomers should be taught to understand what the brackets are
actually doing (effecting operator precedence)

rather nitpicking - again you'll never be able to measure the difference in a
meaningful way, nonetheless my preference goes for single quotes unless the
string literal I have contains a single quote.
explain to your noobs the difference between the quotes and tell them what your
preferences are and why - in the real world they'll come across all the variations
that you/they/me/us/he dislikes so they might as well be given the facts up front, no?
