1.2.1187. Switch With Too Many Default

Switch statements should only hold one default, not more. Check the code and remove the extra default.

PHP 7.0 won’t compile a script that allows for several default cases.

Multiple default happens often with large switch().

<?php

switch($a) {
    case 1 :
        break;
    default :
        break;
    case 2 :
        break;
    default :  // This default is never reached
        break;
}

?>

• Remove the useless default : it may be the first, or the last. In case of ambiguity, keep the first, as it is the one being used at the moment.
