not to display string if variable is null.
I need help making something like this.
so for example Code:
if ($number == NULL) { echo 'there is a $number'; } else { echo 'There is no value'; } |

If the variable is set to null when there is no value, then I think you could check it by using $number === null (three '='). If the variable is not set at all when there's no number then it won't be equal to null so you'd have to use isset($number) to see if it's set.
