Switch, same value for multiple case

Question

switch ($i) {     case A:         $letter = 'first';         break;     case B:         $letter = 'first';         break;     case C:         $letter = 'first';         break;     case D:         $letter = 'second';         break;     default:         $letter = 'third'; } 

Is there any way to shorten first three cases?

They have the same values inside.

Answer 1

switch ($i) {     case A:     case B:     case C:         $letter = 'first';         break;     case D:         $letter = 'second';         break;     default:         $letter = 'third'; } 

Yep there is. If there's no break after a case, the code below the next case is executed too.

Answer 2

switch ($i) {     case A:     case B:     case C:         $letter = 'first';         break;     case D:         $letter = 'second';         break;     default:         $letter = 'third'; }
