function getfunky( $var1, $var2, $var3  = "*NOTUSED*"){
         //how to get funky
                 // with code to ignore $var3 if == *NOTUSED*
}

or
function getfunky( $var1, $var2, $var3  = default){
         //how to get funky
                 // where default == a default value
}

that ZEND thing was confusing to me...
