将数组转换为对象 PHP
I'm creating a simple PHP application and I would like to use YAMLfiles as a data storage. I will get the data as an associative array, with this structure for example:
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，例如使用以下结构：
$user = array('username' => 'martin', 'md5password' => '5d41402abc4b2a76b9719d911017c592')
However, I would like to extend the associative array with some functions and use the ->operator, so I can write something like this:
但是，我想用一些函数扩展关联数组并使用->运算符，所以我可以这样写：
$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
Is there a good way to do this without a class definition?
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？
Basically, I would like to have JavaScript style objects in PHP :)
基本上，我想在 PHP 中有 JavaScript 样式的对象:)

Just cast it:
只需投射它：
$user = (object)$user;
Of course, there are other, more flexible solutions like creating a class that implements ArrayAccess:
当然，还有其他更灵活的解决方案，例如创建一个实现的类ArrayAccess：
$user = new User(); // implements ArrayAccess
echo $user['name'];
// could be the same as...
echo $user->name;

Literally just make a $class = new stdClass;and iterate and reassign. Be aware this is only one level deep, just like typecasting. You would have to write a recursive iterator to get it all. From what I remember Kohana 2/3 has to_object() you can probably use.
字面上只是制作一个$class = new stdClass;并迭代和重新分配。请注意，这只是一层深度，就像类型转换一样。你将不得不编写一个递归迭代器来获得这一切。从我记得 Kohana 2/3 有 to_object() 你可能可以使用。
Found it:
找到了：
class Arr extends Kohana_Arr {
public static function to_object(array $array, $class = 'stdClass')
{
$object = new $class;
foreach ($array as $key => $value)
{
if (is_array($value))
{
// Convert the array to an object
$value = arr::to_object($value, $class);
}
// Add the value to the object
$object->{$key} = $value;
}
return $object;
}
