Here's another quickie: Dead simple one! <?php function x($x) { switch ($x) {

    case 1: return 'bitten';
    case 2: return 'shy';

} }

Surely this should be... function x() {

     static $count = 0;
     $count++;
     switch ($count)
     {
         case 1: return 'bitten';
         case 2: return 'shy';
     }
     return '';

} -Stut

Probably a more accurate solution would be :- function x()

     {
     static $count = 0;
     $count++;
     switch ($count % 3)
         {
         case 0:
         case 2: return 'shy';

         case 1: return 'bitten';
         }
     }			// x

And it's commented :-P

Wow, what a comment. Mine has that comment too, it's just not noise, it's tabs. Where in "Once bitten twice shy" does it say "and if you continue it repeats" ?? -Stut -- http://stut.net/
