PHP Conditional operator

Question

I have the following question(project) and tried a million times, but just can't seem to crack this one

Conditional operator instead of if/else statement

age 12 - 19 should display 'You are a teenager' between 19 and 30 should display 'You are a young adult else 'You are neither a teenager nor a young adult'

Please assist

use a select case or a ternary if block if they've explicitly told you not to use typical if() { } else { } structure but not excluded ternary. — Dave, Apr 23 '15 at 14:26

What if I'm 8 years old? – Blaatpraat Apr 23 '15 at 14:32
age 12 - 19 should display 'You are a teenager' between 19 and 30 should display 'You are a young adult else 'You are neither a teenager nor a young adult' – user3284566 Apr 23 '15 at 14:34
and that`s it :) if 8 years old nothing – user3284566 Apr 23 '15 at 14:35
one variable can`t contain 2 values :) – user3284566 Apr 23 '15 at 14:36
Yeah, missing <12 condition :) But nice code, nicer than other answers ! gz ! – Random Apr 23 '15 at 14:36
<12 condition missing on question :) not in my code ;) – user3284566 Apr 23 '15 at 14:38
nope, the question asks "'else: You are neither a teenager nor a young adult". under 12 is part of the "else"... – Random Apr 23 '15 at 14:39

It is not that hard, and with braces you make it more clear.

echo ($age >= 12 && $age < 19 ? 'You are a teenager' : ($age >= 19 && $age < 30 ? 'You are a young adult' : 'You are neither a teenager not a young adult'));

don't need ` $answer = ` on a ternary if like that you can just do `echo ($age.......` – Dave Apr 23 '15 at 15:49

you can acheive this terenary operator

   echo    if($age>12 && $age<20) ?"You are a teenager":'';
   echo    if($age>19 && $age<31) ?"You are an adult":'';
   echo    if($age>31 && $age<12) ?"You are not an adult nor a teenager":'';

it is asked not to use if/else statements ! – Random Apr 23 '15 at 14:35
still no `if` in ternary, and the last condition is wrong, it should be a `||` operator... – Random Apr 23 '15 at 15:19
