Voorbeeld: example

<?php

class MyClass
{
    public $var1; // This has no explicit default value (technically it has NULL as a default)...
    public $var2 = "xyz";
    public $var3 = 100;
    private $var4;

    public function __construct()
    {
        // Change some properties
        $this->var1 = "foo";
        $this->var2 = "bar";
        return true;
    }
}

$my_class = new MyClass();

$class_vars = get_class_vars(get_class($my_class));

foreach ($class_vars as $name => $value) {
    echo "{$name}: ", var_export($value, true), "\n";
}

?>

var1: NULL
var2: 'xyz'
var3: 100

Voorbeeld: and scoping behaviour

<?php

function format($array)
{
    return implode('|', array_keys($array)) . "\r\n";
}

class TestCase
{
    public $a    = 1;
    protected $b = 2;
    private $c   = 3;

    public static function expose()
    {
        echo format(get_class_vars(__CLASS__));
    }
}

TestCase::expose();
echo format(get_class_vars('TestCase'));

?>

// 5.0.0
a| * b| TestCase c
a| * b| TestCase c

// 5.0.1 - 5.0.2
a|b|c
a|b|c

// 5.0.3 +
