boolean logic - Whats wrong with my if else statement

Question

I have a $name variable containing a string, and when I test it, I never get the "Name should be between 2 and 40 characters" error even when it's less than 2 characters long or more than 40. Why?

if (strlen($name) < 2 && strlen($name) > 40) {
    $nameError = 'Name should be between 2 and 40 characters';
}

Answer 1

How can the length be less than 2 and greater than 40? You want || ("or"), not && ("and").

if (strlen($name) < 2 || strlen($name) > 40) {
