PHP - How to return a variable from a class method?

Question

I don't understand the concept of getter and setter methods in PHP, pls help me out.

Let's say I have this class:

class something()
{
  public function test()
  {
    $bla = 10;
    return $var;
  }
}

How do I get the follwing code to work:

    $something->test();
    echo $bla;

Thanks!

Answer 1

First this:

return $var;

should be:

return $bla;

and second, the second part is wrong and should be like this:

$something = new something();
$bla = $something->test();
echo $bla;

Answer 2

You would need to make $bla global for that to work, which is rarely a good idea.

You would be better off returning that variable, which you could then assign to what you wish when calling the object's method.
