I'd say if anybody should know this for certain, it's somebody who
bothers to benchmark it:
$ time php -r '$s="abc";for($i=0;$i<10000000;++$i);'
real 0m1.966s
user 0m1.634s
sys 0m0.072s
$ time php -r '$s="abc";for($i=0;$i<10000000;++$i) $s=="abc";'
real 0m3.974s
user 0m3.779s
sys 0m0.062s
$ time php -r '$s="abc";for($i=0;$i<10000000;++$i) $s==="abc";'
real 0m2.510s
user 0m2.320s
sys 0m0.056s

If anybody should know this for certain, it's core developers, hence my
question here. I'm curious if type certainty requires an extra check, or a
check less.
Which of these is faster?
if ($str === 'abc') { }
if ($str == 'abc') { }
I expect the triple '=' to be faster, but I'd like to be sure.
Thank you,
Ron
