将PHP对象转换为关联数组

只需打字

$array = (array) $yourObject;

来自 数组 :

如果将对象转换为数组，则结果是一个数组，其元素是对象的属性.键是成员变量名称，但有一些值得注意的例外:整数属性不可访问；私有变量的类名在变量名之前；受保护的变量在变量名前带有"*".这些前置值的两边都为空字节.

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 );

输出:

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

示例:复杂对象

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 );

输出(为清晰起见，已编辑\ 0s):

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

使用var_export而不是var_dump的输出:

Output with var_export instead of var_dump:

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

以这种方式进行类型转换不会对对象图进行深度转换，并且您需要应用空字节(如手册引用中所述)以访问任何非公共属性.因此，这在投射StdClass对象或仅具有公共属性的对象时效果最佳.对于快速又脏的(您要的)，没关系.

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.
