// constructor
function __construct() {

<?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'));
?>
The above example will output:
// 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 + a|b|c a
