Determining a variable type 1

[Nebbish]

Hey all, variable question that I'm sure has been asked before in some form: how do I determine what type a variable is? I'm passing a subroutine arrays and strings, but I don't know how many strings or how many arrays, nor do I know what order they're coming in. So, I have:

sub sample {
	my $var;
	while($var = shift) {
		if(array($var)) {
			foreach my $i (@{$var}) {
				print "is array:", $var[$i], "\n";	
			}
		} else {
			print $var, "\n";
		}
	}
}

I'm looking for something that does what I hoped array($var) would do above.

Check the 'ref' operator, it will return the variable type HASH,HASHREF,SCALAR or ARRAY usually.

way to go siberian I looked for that for ages.
