Is it possible to have a function with two returns like this:

function test($testvar)
{
  // Do something

  return $var1;
  return $var2;
}

Since PHP 7.1 we have proper destructuring for lists. Thereby you can do things like this:

$test = [1, 2, 3, 4];
[$a, $b, $c, $d] = $test;
echo($a);
> 1
echo($d);
> 4

In a function this would look like this:

function multiple_return() {
    return ['this', 'is', 'a', 'test'];
}

[$first, $second, $third, $fourth] = multiple_return();
echo($first);
> this
echo($fourth);
> test

Destructuring is a very powerful tool. It's capable of destructuring key=>value pairs as well:

["a" => $a, "b" => $b, "c" => $c] = ["a" => 1, "b" => 2, "c" => 3];
