switch vs elseif

I've googled, and found some confusing answers. I've tried searching the history of the news group, and only found info on switch or elseif seperately. :( Strictly from a performance stand point, not preference or anything else, is there a benefit of one over the other? for($i=0;$i<3;$i++){ switch($i){ case 0: header pg1 code break; case 1: header pg2 code break; case 3: header pg3 code break; }; }; or would that be better served using an if...elseif structure?
