Php ternary operator giving error

Question

In PHP, if I have a triple type:

$my_thing = $this->myAttribute ? $this->myAttribute : "No attribute was set."; 

can this be reduced?

 $my_thing = $this->myAttribute ?: "No attribute was set." 

It seemed to me that I remember how PHP supported this in its tees, but now I get an error message.

Answer 1

It is supported in PHP 5.3 and higher. From php.net

With PHP 5.3, you can exclude the middle part of the ternary operator. Expression expr1 ?: Expr3 returns expr1 if expr1 is TRUE and expr3 otherwise.
