PHP, Shorthand, If..Else using Ternary Operators

Question

Is there a oneliner for this? A nice Ternary OP?

$F_NAME = $_SESSION[\'USR\'][\'F_NAME\'];
if(isset($_POST[\'F_NAME\'])) {$F_NAME = $_POST[\'F_NAME\'];}
         


        

Answer 1

Its supposed to be:

(conditions) ? true : false
   satisfies <--^      ^----> did not satisfy

So this equates into:

$F_NAME = isset($_POST['F_NAME']) ? $_POST['F_NAME'] : $_SESSION['USR']['F_NAME'];
