Are there any best practices or guidelines for implementing a custom __toArray() method in PHP classes for more controlled array conversion?

When implementing a custom `__toArray()` method in PHP classes, it's important to follow best practices to ensure controlled array conversion. This can help in maintaining consistency and predictability when converting objects to arrays. One approach is to only include specific properties that need to be exposed in the array representation, and to handle nested objects or arrays appropriately. 

class MyClass {
    private $property1;
    private $property2;

    public function __construct($property1, $property2) {
        $this->property1 = $property1;
        $this->property2 = $property2;
    }

    public function __toArray() {
        return [
            'property1' => $this->property1,
            'property2' => $this->property2,
        ];
    }
}

$obj = new MyClass('value1', 'value2');
$arrayRepresentation = $obj->__toArray();
