It's not allowed.

One alternative if you want to skip any argument and you can't rearrange the
skippable ones all towards the end is to pass an associative array instead,
which make it looks like named parameters from other languages, e.g.:

myfunction(array(
arg2 => 'wibble',
arg6 => 'wobble'
));
