Re: Using Shift with Parameters in a subroutine

[Marshall]

It appears to me that you are only passing 2 refs to the sub.

sub foo{
  my ($query_ref, $session_ref) = @_;
}

These refs should be references to hash tables.

In general, passing 10 parameters to a sub is not a good idea. Better is reference to a hash.

Just to be thorough,

my ($one, $two) = _@;

works once, but ignores the side effect of shift (removing the arguments from the @_ array).

As Marshall says, using a reference to an array would be the best way to deal with a lot of parameters, but if you wanted to, say, process two at a time, you could do

while (my ($one,$two) = splice @_, 0, 2) {
    #do something
}

(you'll get an uninitialized value warning if you supply an odd number of parameters)

thanks. i didnt realise this earlier, about the impact on @_ .

[perlron]

ok. ill improvise then. thanks. the 10 parameters was purely hypothetical , as a programming possibility. thats all.
