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?

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.

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