Answer 1

If you have simple conditions, like if something equates to something else, then a switch is ideal.

For example, instead of doing the following:

if($bla == 1) {

} elseif($bla == 2) {

} elseif($bla == 3) {

} etc...

It's better to do it like this:

switch($bla) {
  case 1:
    ...
    break;
  case 2:
    ...
    break;
  case 3:
    ...
    break;
  default:
    ...
    break;
}

Alternatively, if you have complex conditions, you should use an if/else.

I think that this is all a matter of opinion though - some people just don't use switch statements at all, and stick with if/else.
