That's one person's opinion - and his test is full of holes.  For
instance - a timing loop like he shows is worthless in a multitasking
system.  Too many other things are going on; even a timer interrupt
during the loop can change timings.  You need to have a clean machine
(NOTHING else - including network, etc.) running to start.  No
paging/swapping.  Even then such tests are suspect because you can't
stop everything.  Running on a single tasking system such as MS-DOS
would be better, but still not necessarily accurate.

It's also only valid for one version of PHP - the one he's using.
Different versions can operate differently.

His whole argument is based on his statement: "I hold the opinion that
microoptimization like that is just pointless.".  Good programming
practice is not microoptimization!

And the killer is this statement: "Now some may argue: PHP is an
interpreted language, so compile time actually also happens at runtime.
My response to that would normally be: Use APC."  That MAY be find if
you're running your own server.  But most people aren't, and APC is not
available to him.

I could go on, but the bottom line is - he is obviously biased, and his
arguments are full of holes.  I agree with J.O. - single quotes are
better unless you need to parse the strings.
