You have 2 options:

1. return value from the function:

<?php

class example
{
    public $db;

    function __construct($db)
    {
        $this->db = $db;
    }

    function test()
    {
        return "okokok";
    }
}

$a = new example("");

$c = $a->test();

echo $c;

?>

2. assign value to class instance property:

<?php

class example
{
    public $db;
    public $value;

    function __construct($db)
    {
        $this->db = $db;
    }

    function test($v)
    {
        $this->value = $v;
    }
}

$a = new example("");

$c = $a->test("new value");

echo $a->value;

?>
