  • Job security?
Tips for Using Ternary Operators

Here are a few tips for when using “?:” logic:

  • Don’t go more levels deep than what you feel comfortable with maintaining.
  • If you work in a team setting, make sure the other programmers understand the code.
  • PHP.net recommends avoiding stacking ternary operators. “Is [sic] is recommended that you avoid “stacking” ternary expressions. PHP’s behaviour when using more than one ternary operator within a single statement is non-obvious.”
  • If you aren’t experienced with using ternary operators, write your code using if/else first, then translate the code into ?’s and :’s.
  • Use enough parenthesis to keep your code organized, but not so many that you create “code soup.”
More Sample Usage

Here are a couple more uses of ternary operators, ranging from simple to advanced:

/* another basic usage */

/* shorthand usage */
$message = 'Hello '.($user->get('first_name') ?: 'Guest');
/* echo, inline */
echo 'Based on your score, you are a ',($score > 10 ? 'genius' : 'nobody'); //harsh!
