Convert PHP object to associative array

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

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


Just typecast it

$array =  (array) $yourObject;


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.

Example: Simple Object

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

var_dump( (array) $object );


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

Example: Complex Object

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 );

Output (with \0s edited in for clarity):

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

Output with var_export instead of var_dump:

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

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.
