Personally, I hate trailing {'s
I think this
function blah()
{
switch( $bob )
{
case 1:
$var = "whatever";
break;
}
}
Is much easier to read and follow. As for the exiting question...
The "proper" way is to use the breaks. "They" say that multiple returns in
any function = bad programming. The .0001 second that it takes to break and
return the value will never matter.
Plus, you or someone else may have to add to that function later. Let's say
I wanted to add "</B>" to the end of $retval. If you use the normal way I
can just make one change, return $retval . "</B>"; instead of changing 3
different returns.
