PHP strlen question

Question

Ok I am checking that a string is at least 4 characters long and 25 or less characters short

I tried to use strlen like this

$userNameSignupLength = strl         


        

Answer 1

I think you want an OR there:

else if($userNameSignupLength < 4 || $userNameSignupLength > 25) {

Like Gumbo said, the length cannot possibly be both less than 4 AND greater than 25. && means and.
