These prepended values have NUL bytes on either side.

范例

示例 #1 get_mangled_object_vars() example

<?php

class A
{
    public $public = 1;

    protected $protected = 2;

    private $private = 3;
}

class B extends A
{
    private $private = 4;
}

$object = new B;
$object->dynamic = 5;
$object->{'6'} = 6;

var_dump(get_mangled_object_vars($object));

class AO extends ArrayObject
{
    private $private = 1;
}

$arrayObject = new AO(['x' => 'y']);
$arrayObject->dynamic = 2;

var_dump(get_mangled_object_vars($arrayObject));

以上例程会输出：

array(6) {
  ["Bprivate"]=>
  int(4)
  ["public"]=>
  int(1)
  ["*protected"]=>
  int(2)
  ["Aprivate"]=>
  int(3)
  ["dynamic"]=>
  int(5)
  [6]=>
  int(6)
}
array(2) {
  ["AOprivate"]=>
  int(1)
  ["dynamic"]=>
  int(2)
}
