What are the best practices for storing and managing member data within a PHP class or object for easy retrieval and manipulation?

Storing and managing member data within a PHP class or object can be done efficiently by using private properties and public methods for retrieval and manipulation. By encapsulating the data and providing controlled access through methods, you can ensure data integrity and maintainability.

class Member {
    private $name;
    private $age;

    public function setName($name) {
        $this->name = $name;
    }

    public function getName() {
        return $this->name;
    }

    public function setAge($age) {
        $this->age = $age;
    }

    public function getAge() {
        return $this->age;
    }
}

$member = new Member();
$member->setName('John Doe');
$member->setAge(30);

echo $member->getName(); // Output: John Doe
echo $member->getAge(); // Output: 30
