>it's just my coding style to use only double quotes

I've seen horrific code with a lot of escaping, concatenation, single-
and double quotes mixed within to build a complex SQL query. It can be
really hard to find a missing quote in such a mess, but YMMV.

Not necessarily. In the UCNs on php.net you'll find "benchmarks" that
state one or the other

And performance is hardly ever a reason when printing out something.
BTW, the fastest would probably be an echo with a comma-separated list
of arguments.
