(PHP 4, PHP 5, PHP 7, PHP 8)
A generic empty class with dynamic properties.
Objects of this class can be instantiated with new operator or created by typecasting to object. Several PHP functions also create instances of this class, e.g. json_decode(), mysqli_fetch_object() or PDOStatement::fetchObject().
Despite not implementing __get()/__set() magic methods, this class allows dynamic properties and does not require the #[\AllowDynamicProperties] attribute.
This is not a base class as PHP does not have a concept of a universal base class. However, it is possible to create a custom class that extends from stdClass and as a result inherits the functionality of dynamic properties.
This class has no methods or default properties.
Ejemplo #1 Created as a result of typecasting to object
<?php
$obj = (object) array('foo' => 'bar');
var_dump($obj);El resultado del ejemplo sería:
object(stdClass)#1 (1) { ["foo"]=> string(3) "bar" } Ejemplo #2 Created as a result of json_decode()
<?php
$json = '{"foo":"bar"}';
var_dump(json_decode($json));El resultado del ejemplo sería:
object(stdClass)#1 (1) { ["foo"]=> string(3) "bar" } Ejemplo #3 Declaring dynamic properties
<?php
$obj = new stdClass();
$obj->foo = 42;
$obj->{1} = 42;
var_dump($obj);El resultado del ejemplo sería:
object(stdClass)#1 (2) { ["foo"]=> int(42) ["1"]=> int(42) }
