Question

Can a PHP function return a lot of vars without array?

I want like that:

<?php

public function a()
{
   $a = "a";
   $b = "b";
   $c = "c";

}

echo a()->a;
echo a()->b;
echo a()->c;

?>

How can I access to $a,$b,$c vars?

Instead of an array, you could use an associative array and cast it to an object, which allows you to access the elements using the -> object syntax:

function a()
{
  return (object) array(
    'a' => "a",
    'b' => "b",
    'c' => "c");
}

echo a()->a;  // be aware that you are calling a() three times here
echo a()->b;
echo a()->c;
