This way if you want your code to be decently portable between languages, if that's a concern. Which is also usable in PHP in the same way. For all other cases adapt your code accordingly. Though be pleasantly surprised is they are. So you should never expect the same behavior in any of them. Not all languages do things the same way. To learn more about ternary operators and usage, visit PHP.net Comparison Operators.

$message = 'Hello '.($user->get('first_name') ?: 'Guest') /* echo, inline */Įcho 'Based on your score, you are a ',($score > 10 ?

'behind' : 'above average')) // returns 'You are behind' /* "thankfully-you-don't-need-to-maintain-this" level */ $message = 'Hello '.($user->is_logged_in() ? $user->get('first_name') : 'Guest') /* shorthand usage */ Here are a couple more uses of ternary operators, ranging from simple to advanced: /* another basic usage */

Use enough parenthesis to keep your code organized, but not so many that you create "code soup.".

If you aren't experienced with using ternary operators, write your code using if/else first, then translate the code into ?'s and :'s.

I preach a lot about using shorthand CSS and using MooTools to make JavaScript relatively shorthand, so I look towards PHP to do the same.

If / Else statements are great but they can be too long. If / Else statements are easy to code and global to all languages. An essential part of programming is evaluating conditions using if/else and switch/case statements.
