get_mangled_object_vars()

get_mangled_object_vars() — Returns an array of mangled object properties.

Built-in function of PHP 8.5. The manual lists it as available in PHP 7 >= 7.4.0, PHP 8. This page is the reference card: signature, parameters and return value, plus the changelog and the example the manual provides.

What it does

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.

Signature

Parameters

Parameter	Type	What it takes
$object	object	An object instance.

Return value

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

Example

A runnable snippet:

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));

Output:

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) }
