How to convert an object to an array in PHP?
Use (array) to convert simple objects into arrays. If they contain private or protected properties, the key names will have special characters; for nested objects, recursive functions should be used to traverse the conversion to ensure that all hierarchical objects become associative arrays.
To convert an object to an array in PHP, you can use a simple type casting method or a recursive approach depending on the complexity of the object.
Using Type Casting (Simple Objects)
If the object contains only public properties and no nested objects, type casting with (array) works directly.
$object = new stdClass(); $object->name = "John"; $object->age = 30; $array = (array) $object; print_r($array);
This outputs:
Array
(
[name] => John
[age] => 30
)
Handling Private and Protected Properties
When an object has private or protected properties, casting to array includes additional characters in the keys to indicate visibility.
- Private property myProp in class MyClass becomes "\0MyClass\0myProp"
- Protected properties become "\0*\0propertyName"
This can complicate access, so consider using getters or reflection if you need clean array keys.
Converting Nested Objects or Complex Data
For objects containing other objects or arrays, a recursive function ensures full conversion.
function objectToArray($data) {
if (is_object($data)) {
$data = get_object_vars($data);
}
if (is_array($data)) {
return array_map('objectToArray', $data);
}
return $data;
}
// Example usage
class Address {
public $city = "New York";
public $zip = "10001";
}
class Person {
public $name = "Alice";
public $address;
public function __construct() {
$this->address = new Address();
}
}
$person = new Person();
$array = objectToArray($person);
print_r($array);
This approach ensures all levels of nested objects are converted into associated arrays.
Basically, use (array) for simple cases, and a recursive function when dealing with complex or nested objects.
