Switch on a range

[ayzee]

Right o guys and gals, solve this for me and I'll give you a golden carrot!

I want to perform a switch on a range of numbers, for example:

switch($var)
{
   case 0 to 15:
      //exc code
      break;
   case 16 to 30:
      //exc code
      break;
   case 31 to 45:
      //exc code
      break;
   case 46 to 59:
      //exc code
      break;
}

BTW - I know you can use an if statement instead but I'm curious about the possibility of using a switch.

If you want match this specific criteria then you can use

switch( (int)(($var-1) / 15) ) {

  // 0..15
  case 0:
    // code
    break;

  // 16..30
  case 1:
    // code
    break;

  // 31..45
  case 2:
    // code
    break;

  // 46..59
  case 3:
    // code
    break;

}

But if you want to compare your $var to other different values you need to you if...elseif

if( $var >= 0 ) {
  if( $var <= 15 ) {
    // code
  } elseif ( $var <= 30 ) {
    // code
  } elseif ( $var <= 45 ) {
    // code
  } elseif ( $var <= 59 ) {
    // code
  }
}

Brilliant!

Whilst reading it I thought to myself "Why didn't I think of that?" - then I answered myself "'cause I'm not that clever...durrr!"

here you go sir, one golden carrot (well, three actually).

Thank you very much.
