I'd agree, but I'd also say:

1.) Test, test, test... It'll take 5 minutes to run a quick benchmark
and find out.

2.) My guess is that neither is going to have a significant performance
impact, and that it's probably not worth worrying about in the big
picture.  Look for low-hanging fruit first, if you're optimizing your
app.  Now, on the other hand, if the real-world example is concatenating
a million different lines of text before printing, that could add up...

Well,

My guess (no facts here) would be the first is slower.

First the "'s need to be checked for $variables, it would be quicker to
put '.
And then an operation of copying needs to be done. Allocation as well on
the c side for the new, larger variable.

Then the display.

The second snippet displays the lines without the additional operation
of allocation/concatenation.

Who knows though..I'd like a more fact based explanation.
