Re: Boolean Parameter to 3 Options?

Why not this: function doFooBar($doFoo = 0) { switch ($doFoo) { case 2: echo "Did Baz"; break; case 1: echo "Did Foo"; break; default: echo "Did Bar"; break; } } I think in this way you can avoid future problems in case you need to add other options in this param. Hope helps.
