chris, this might help too, it's a slight variation of what Laith sent
you but is the way it's more commonly used function getfunky( $var1,
$var2, $var3  = ""){
  if(!empty($var3){
   do whatever
  }
}
That's probably the practicality that most people would use. IF $var3
ends up having a value the null will get overridden just fine.

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...
