get_mangled_object_vars

(PHP 7 >= 7.4.0, PHP 8)

get_mangled_object_varsReturns an array of mangled object properties

说明

get_mangled_object_vars(object $object): array

Returns an array whose elements are the object's properties. The keys are the member variable names, with a few notable exceptions: private variables have the class name prepended to the variable name, and protected variables have a * prepended to the variable name. These prepended values have NUL bytes on either side. Uninitialized typed properties are silently discarded.

参数

object

An object instance.

返回值

Returns an array containing all properties, regardless of visibility, of object.

范例

示例 #1 get_mangled_object_vars() example

<?php

class A
{
    public 
$public 1;

    protected 
$protected 2;

    private 
$private 3;
}

class 
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)
}
