possible to do this in 1 line

Question

I have a function that returns an array of named values ['upper','lower','chosen']. To read the upper value, I do this

$returned = myfunction($input1, $input2);
$upper = $returned['upper'];

Is there any way to get it all done in 1 line, maybe like this, but this syntax doesn't work. Any other way?

$upper = myfunction($input1, $input2)['upper'];

Answer 1

You can do something like:

 list ($upper, $lower, $chosen) = myfunction($input1, $input2);

Answer 2

Your function could return an object instead of an array. Then you could do something like this :

class myObject {
    public $upper;
    public $lower;
    public $chosen;
}

$upper = myFunction($input1,$input2)->upper;

Answer 3

If upper is always the first element, you can use array_shift():

$returned = array_shift(myfunction($input1, $input2));
