i was under the (perhaps misguided) impression that the

'do_something() if $condition'

form would be marginally faster than the

'if ($condition) { do_something() }'

as the second form opens a block, and thereby a new scope, which requires extra work.

while it seems to be the case that the first form is indeed marginally faster, it really is marginal. thanks for the benchmarks guys!
