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
