What is the best practice for defining and accessing arrays within PHP classes?

When defining arrays within PHP classes, it is best practice to declare them as protected or private properties to encapsulate them within the class. This helps in maintaining data integrity and ensures that the array is only accessed and modified through class methods. To access the array within the class, you can create getter and setter methods to retrieve and update the array elements. 

class MyClass {
    private $myArray = [];

    public function getMyArray() {
        return $this->myArray;
    }

    public function setMyArray($array) {
        $this->myArray = $array;
    }
}
