In PHP using Ternary Operator without the Else statement

Question

How can I write a conditional statement like this?

$admin = ($user['permissions'] == 'admin') ? true;

Please note that there is no else statement. Is it possible to write this without else?

Answer 1

No... ternary means three parts you need the condition, the true part, and the false part

You cannot build a ternary operator with only one expected result. Its simple Boolean logic, it just returns two values.

I would suggest you just stick with the first if/else statement you have. Besides using ternary operators can be harder to read in comparison to the standard if/else statements.

However since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.

Answer 2

You cannot, it requires 3 parts for that shortcut if:else
