So i have a php class and i'm having a small snarl up. imagine a class as one shown below

```
<?php
class Foo
{
   public function __construct()
  {
     $this->bar1();
  }
  public function bar1()
  {
    $myvar = 'Booya!';

   return 'Something different';
  }
  public function bar2()
  {
    //get value of $myvar from bar1()
  }
}
$new_foo = new Foo();
$new_foo->bar2();
?>

```

Question is, 
how do I access the variable `$myvar` from `bar1()` keeping in mind that `bar1()` returns something different.
