如何在序列化期间隐藏类的属性？

can i override function that is responsbile for serializing and Php class to an array/stdclass so that i can implement my own logic "like hiding certain attributes based on condition)

class UserModel{
  $hidden = ['password'];

  function __construct(array $data) {
    foreach($data as $key=>$value)$this->$key = $value;
  }

}

$user = new UserModel(['id'=>1,'password'=>123]);

var_dump($user);

How about implementing the Serializable interface? Looks like you can do your custom logic by implementing the interface methods.

Example:

class UserModel implements Serializable {

    // returns string
    public function serialize() {
        $data = array(
            'id' => $this->id,
            'password' => null, // or omit password
            'email' => $this->email,
            ...
        );
        return serialize($data);
    }
}

You can overwrite a method

Just look at the small exemple of the classe below;

 class User { 
 //To hide
 private $pass;

 //To show
 private $log;
 private $nbPoints;

  {...}
  public function serialize()
  {
    $arr = [];
    $arr['LOG'] = $this->log;
    $arr['POINTS'] = $this->nbPoints;
    return ($arr);
  }
}

You can var_dump the return of the User->serialize method and password will ne be showed.

If you need all your class, then crypt or hash all variable you need to hide.

Here is two famous (but unsafe) method in cryptology : MD5 Ceaser cipher

Just understand well the difference between hashing and crypting datas

(HASH : https://en.wikipedia.org/wiki/MD5);

(CRYPTING : https://en.wikipedia.org/wiki/Caesar_cipher);
