Hi,
I want to check between number.
for example:
function (10, 18, 20)
check (18) if is between 18 - 20 and get true or false.
thanks.

function is_between($number, $min, $max)
{
  $result = ($number >= $min and $number <= $max) ? TRUE : FALSE;
  return($result);
}

(You can change the order of the arguments as desired to whatever makes sense to you, i.e. function is_between($min, $number, $max).)
