문자열을 사용하여 PHP 클래스 속성에 어떻게 액세스합니까?

class MyClass {
  public $name;
}

$obj = new MyClass();
$obj->name = 'John Doe';

// Using dynamic property access
$property = 'name';
echo $obj->$property; // Output: John Doe

echo $obj->name;

class MyClass implements ArrayAccess {
  public $name;

  public function offsetExists($offset) {
    return property_exists($this, $offset);
  }

  public function offsetGet($offset) {
    return $this->$offset;
  }

  public function offsetSet($offset, $value) {
    $this->$offset = $value;
  }

  public function offsetUnset($offset) {
    unset($this->$offset);
  }
}

$obj = new MyClass();
$obj['name'] = 'John Doe';

echo $obj['name']; // Output: John Doe
