Functions and defaults

[Bob Stearns]

Consider a function header:

function init($name, $ttl, $need_bhid="N", $need_entity_id ="N")

What values do the last two parameters have when it is called with the
following arguments:

init("name", "do name",,"Y");

That's a syntax error.

That is too bad. It really should be "N" and "Y" with PHP honoring the
default values for all omitted arguments, not just trailing ones. Does
PHP v 5.x do it better?

No, C++-style skipping arguments in the middle of a list of arguments with
defaults is not supported in any current version of PHP.

(I don't know whether will be or not in PHP 6).

Put me down for a positive vote if one is being taken :-)
