stdclass
ENTITY
A generic empty class with dynamic properties.
Objects of this class can be instantiated with the 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 stdClass and as a result inherits the functionality of dynamic properties.
ENTITY
#[\AllowDynamicProperties]
stdClass
This class has no methods or default properties.
ENTITY
Created as a result of typecasting to object
<?php
$obj = (object) array('foo' => 'bar');
var_dump($obj);
ENTITY
object(stdClass)#1 (1) {
["foo"]=>
string(3) "bar"
}
Created as a result of json_decode
<?php
$json = '{"foo":"bar"}';
var_dump(json_decode($json));
ENTITY
object(stdClass)#1 (1) {
["foo"]=>
string(3) "bar"
}
Declaring dynamic properties
<?php
$obj = new stdClass();
$obj->foo = 42;
$obj->{1} = 42;
var_dump($obj);
ENTITY
object(stdClass)#1 (2) {
["foo"]=>
int(42)
["1"]=>
int(42)
}
