Hi,
Although this is not as hot as references or Unicode stuff, I would like to
discuss a new topic.
Currently PHP accepts more parameters to a function than the required.
In English:
<?
function a($b) {}
a(1,2,3);
?>
PHP accepts this and generates no errors. My purpose is to start generating
an E_NOTICE, just like we do for not yet initialized variables.
This behaviour has already beaten me for a couple of times, because I had a
program with functions with similar names, but with different number of
parameters. The result for calling the wrong function? A nice infinite loop
:)
I hope this is not hard to implement (maybe in the parser, to get the errors
on compile time - for performance).
Regards,
Nuno

This would break BC (btw a hot topic nowadays, too ;) ) so this is not a
good idea. Also it makes no sense in an oo-driven environment as long as
there is no way of overloading methods.
Best way to deal with this is to write gateway methods that delegate to the
appropriate methods based on the passed in parameters.

No, stupid output!
Generating E_NOTICE is not a good idea. You don't need to create
functions with variable arguments count like printf()?

No, I at least I think I've never created such a function. To be sincere,
I've not even remembered of such functions when I was writing that e-mail :)
So, I think my suggestion is bogus.. Although a special syntax (copied from
C) could be introduced.. well maybe not..

This is expected behaviour in PHP! Since PHP does not offer true
overloading of method headers (multiple methods or functions with the
same name but different parameter lists) this is badly needed.

Hello Jani,

Yep no way! PHP doesn't offer a '...' signature so we need it the way it is.
And i don't think we want to have those '...' signatures.

No way, we have func_get_arg() for this, do to some kind of overloading.
