OK, something's awry!
I'm running on a 4800+ X2 (although running a script like this will
effectively only use a single 2.4GHz processor with a 1MB cache) using
PHP 5.1.2 on Gentoo (desktop) and I get the following output:
S Diff: 1.131... (keeping your level of precision)
D Diff: 1.109... (keeping your level of precision)
This shows that double quotes are faster?!
I'll happily post a video of it happening if anyone disbelieves the
results... I haven't modified the script (except to take out the extra
two } that cause syntax errors).

OK, here my results agree with yours (although mine only has it 3% faster
not the 24% yours shows).
Anyway, if the server can throw out 100,000 (near as damn it) prints
(which is way more than any sane script would do) in a second using either
the fastest or slowest method +/-3% then I'll stick to my normal method.
However, are my results unique. Can anyone else run this test besides me
and Carl so I can see if I've got a mean, lean (and unique) PHP machine :-)
Cheers,
Andy
