转换PHP对象关联数组 [英] Convert PHP object to associative array

问题描述

我整合到我的网站，而我的code使用数组写入与存储在数据对象工作的API。

I'm integrating an API to my website which works with data stored in objects while my code is written using arrays.

我要一个快速和肮脏的功能，将对象转换为一个数组。

I'd like a quick and dirty function to convert an object to an array.

推荐答案

只是强制转换为

$array =  (array) $yourObject;

从<一个href=\"http://www.php.net/manual/en/language.types.array.php\">http://www.php.net/manual/en/language.types.array.php

如果一个对象被转换成一个阵列，其结果是一个数组，其元素为对象的属性。键是成员变量名，有几个明显的例外：整数属性不可访问;私有变量有ppended的变量名的类名$ P $;受保护的变量有ppended的变量名'*'$ P $。这些prepended值具有空字节两边。

If an object is converted to an array, the result is an array whose elements are the object's properties. The keys are the member variable names, with a few notable exceptions: integer properties are unaccessible; private variables have the class name prepended to the variable name; protected variables have a '*' prepended to the variable name. These prepended values have null bytes on either side.

示例：简单对象

$object = new StdClass;
$object->foo = 1;
$object->bar = 2;

var_dump( (array) $object );

的输出：的

array(2) {
  'foo' => int(1)
  'bar' => int(2)
} 

示例：复杂的对象

class Foo
{
    private $foo;
    protected $bar;
    public $baz;

    public function __construct()
    {
        $this->foo = 1;
        $this->bar = 2;
        $this->baz = new StdClass;
    }
}

var_dump( (array) new Foo );

的输出（为清楚起见编辑在\\ 0）：的

array(3) {
  '\0Foo\0foo' => int(1)
  '\0*\0bar' => int(2)
  'baz' => class stdClass#2 (0) {}
}

的与输出 var_export 而不是的var_dump ：的

Output with var_export instead of var_dump:

array (
  '' . "\0" . 'Foo' . "\0" . 'foo' => 1,
  '' . "\0" . '*' . "\0" . 'bar' => 2,
  'baz' => 
  stdClass::__set_state(array(
  )),
)

类型转换这种方式不会做对象图深铸造和需要应用的空字节（如手动报价解释）访问任何非公开的属性。所以这个效果最好时，铸造一个StdClass对象或唯一的公共属性的对象。为了快速和肮脏（你问什么），它的罚款。

Typecasting this way will not do deep casting of the object graph and you need to apply the null bytes (as explained in the manual quote) to access any non-public attributes. So this works best when casting StdClass objects or objects with only public properties. For quick and dirty (what you asked for) it's fine.
