Changelog:

5.0.3

get_class_vars()

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.

Examples:

get_class_vars() example

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

var1 :
var2 : xyz
var3 : 100

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
