# get_class_vars

(PHP 4, PHP 5)

get_class_vars — Get the default properties of the class

### Description

array get_class_vars ( string `$class_name` )

Get the default properties of the given class.

### Parameters

`class_name`

  The class name

### Return Values

Returns an associative array of declared properties visible from the current scope, with their default value. The resulting array elements are in the form of varname => value. In case of an error, it returns `FALSE`.

### Changelog

Version | Description
--- | ---
5.0.3 | Depending on the scope, 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.
4.2.0 | Uninitialized class variables are now also reported by get_class_vars().

### Examples

Example #1 get_class_vars() example

`<?php
class myclass {
var $var1; // this has no default value...
var $var2 = "xyz";
var $var3 = 100;
private $var4; // PHP 5
// constructor
function myclass() {
// 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";
}
?>`

The above example will output:

    // Before PHP 4.2.0
    var2 : xyz
    var3 : 100

    // As of PHP 4.2.0
    var1 :
    var2 : xyz
    var3 : 100

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'));
?>`

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
