[PHP] if/elseif/else v. switch

[Dennis Seavers]

Is there any noticeable difference (on the part of the client) between identical 
conditionals, one written as a switch, the other written as an if, elseif ... else 
conditional?  I realize that one programmer coming in behind another might prefer the 
gentler layout of a switch; but would there be any perceivable difference, 
client-side, between the options?
