    var $helpers = array ('Html','Form');
    var $name = 'Posts';

    function index() {
        $this->set('posts', $this->Post->find('all'));
    }
}
?>

使用 public 和使用 var 有什么区别？

Answer 1

var 已弃用 visibility在功能上等同于 public 的关键字。

来自文档:

Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword). In PHP 5 before 5.1.3, its usage would generate an E_STRICT warning.

由于它已被关键字 public 取代，新蛋糕遵循新标准。查看工作示例 here .
