Question

I am new to PHP and trying to learn things.

Is it posible to avoid the use of temporary variables ?

<?php

    function get_name()
    {
        // assume that this function return 3 
        // values on different conditions "name0" "name1" or "name2";
    }

    $result =  ( get_name() == "name0" || get_name() == "name1") ? "Primary" : "Secondary" ;
    echo $result;

?>

on the above i am calling the get_name() function two times , which means two calls on the same function.

Is it possible to achieve the same with just one call without saving it into a temporary variable?

What is the commonly used practices ?

Update : I edited the question to be more specific.Almost all answers are satisfactory,Hope that this update will help for new readers.

I would do that:

$result =  in_array(get_value(), array(0, NULL), true) ? "Zero" : "One" ;
