I usually use 1, or maybe 2 if there is other 'stuff' I'm putting in $string other than just $var1/2/3. Personal preference I guess.
Are you concerned with speed / overhead of one operation versus another? I'm guessing that micro-optimization won't make much difference - although I haven't benchmarked, so don't know for sure.
