PHP - associative array as an object [duplicate]

Question

Convert Array to Object PHP

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') 

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 

Is there a good way to do this without a class definition?

Basically, I would like to have JavaScript style objects in PHP :)

Just cast it:

$user = (object)$user; 

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;
