function in ()
{
	if (func_num_args() < 2)

	$haystack = func_get_args();
	$needle   = array_shift($haystack);
	
	return in_array($needle, $haystack) ? TRUE : FALSE;
}

if (in('foo', 'bar', 'foobar', 'foo')) //... TRUE
if (in('foo', 'bar', 'foobar', 'baz')) //... FALSE
if (between(15, 10, 20)) //... TRUE
I'm not sure if you want >= and <= instead in between(), but you can 
just change it yourself.
