TRUE : FALSE; } Don't make PHP do more work than it needs to: return ($var > $min && $var < $max) is quite sufficient. > > function in () > { > if (func_num_args() < 2) > trigger_error('You must provide at least one > argument for in()', > E_USER_WARNING); > > $haystack = func_get_args(); > $needle = array_shift($haystack); > > return in_array($needle, $haystack) ? TRUE : FALSE; } return in_array($needle, $haystack) Also, you may find array_splice($haystack, 0, 1) more efficient, since array_shift() renumbers all the keys. ($needle = $haystack[0]; unset $haystack[0]; would be another possibility.) Cheers!
