PHP - 作为对象的关联数组
可能重复:
将数组转换为PHP对象
我正在创建一个简单的 PHP 应用程序，我想使用 YAML 文件作为数据存储.我将数据作为关联数组获取，例如以下结构:
I'm creating a simple PHP application and I would like to use YAML files as a data storage. I will get the data as an associative array, with this structure for example:
$user = array('username' => 'martin', 'md5password' => '5d41402abc4b2a76b9719d911017c592')
但是，我想用一些函数来扩展关联数组并使用 -> 运算符，所以我可以这样写:
However, I would like to extend the associative array with some functions and use the -> operator, so I can write something like this:
$user->username = 'martin'; // sets $user['username']
$user->setPassword('hello'); // writes md5 of 'hello' to $user['md5password']
$user->save(); // saves the data back to the file
在没有类定义的情况下，有没有一种好方法可以做到这一点?
Is there a good way to do this without a class definition?
基本上，我想在 PHP 中使用 JavaScript 样式的对象 :)
Basically, I would like to have JavaScript style objects in PHP :)
推荐答案
投吧:
$user = (object)$user;
当然，还有其他更灵活的解决方案，例如创建一个实现 数组访问:
Of course, there are other, more flexible solutions like creating a class that implements ArrayAccess:
$user = new User(); // implements ArrayAccess
echo $user['name'];
// could be the same as...
echo $user->name;
