### Istoricul schimbărilor

Versiune | Descriere
--- | ---
5.0.3 | get_class_vars() will only return the properties that can be accessed from the current scope.
5.0.2 | Calling get_class_vars() will now expose all the properties as an array, unlike previous behaviour where protected and private properties were prefixed with nul bytes.
5.0.1 | Calling get_class_vars() will expose all properties, as when converting an object to a class.

### Exemple

Example #1 get_class_vars() example

`<?php
class myclass {
var $var1; // this has no default value...
var $var2 = "xyz";
var $var3 = 100;
private $var4;
// constructor
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 : $value\n";
}
?>`

Example #2 get_class_vars() 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'));
?>`

Exemplul de mai sus va afișa:

    // 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 +
