Re: a performance question

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
