[PHP] Attributes vs. Accessors

[Philip Thompson]

Hi all.

Curious. Which do you prefer and why?
<?php
class Hello {
    public $hi;

    function __construct () {
        $this->hi = 'Well Hello There!';
    }

    function hi () {
        return $this->hi;
    }
}

$hello = new Hello ();

// Access the value this way...
echo $hello->hi;

// or the accessor...
echo $hello->hi();
?>

For publicly-declared variables, do you access the attribute directly  
or use an accessor?
