Est-il possible d'enchaîner statique avec la méthode non statique en PHP?

Question

Voici mon exemple de code classe utilisateur mais ne fonctionne pas quand j'ai ajouté la méthode statique avec les méthodes publiques:

<?php 

namespace App\Classic; 

class User 
{ 
    public $username; 
    public static $upassword; 
    public $age; 
    public $message; 

    public function username($username) 
    { 
     $this->username = $username; 
     echo $this->username."<br>"; 
     return $this; 
    } 

    public static function password($upassword) 
    { 
     self::$upassword = $upassword; 
     echo self::$upassword."<br>"; 
    } 

    public function age($age) 
    { 
     $this->age = $age; 
     echo $this->age."<br>"; 
     return $this; 
    } 

    public function message($message) 
    { 
     $this->message = $message; 
     echo $this->message."<br>"; 
     return $this; 
    } 
} 

et ceci est l'effet secondaire de la méthode enchaînant:

$user = new User(); 
$user::password('secret') 
    ->username('admin') 
    ->age(40) 
    ->message('lorem ipsum');

Je ne sais pas Quelle est la logique derrière cela, mais cette solution sera toujours utile.

Try this code snippet here

<?php 

namespace App\Classic; 

ini_set('display_errors', 1); 

class User 
{ 

    public $username; 
    public static $upassword; 
    public static $currentObject=null;//added this variable which hold current class object 
    public $age; 
    public $message; 

    public function __construct()//added a constructor which set's current class object in a static variable 
    { 
     self::$currentObject= $this; 
    } 
    public function username($username) 
    { 
     $this->username = $username; 
     echo $this->username . "<br>"; 
     return $this;//added this statment which will return current class object 
    } 

    public static function password($upassword) 
    { 
     self::$upassword = $upassword; 
     echo self::$upassword . "<br>"; 
     return self::$currentObject; 
    } 

    public function age($age) 
    { 
     $this->age = $age; 
     echo $this->age . "<br>"; 
     return $this; 
    } 

    public function message($message) 
    { 
     $this->message = $message; 
     echo $this->message . "<br>"; 
     return $this; 
    } 

} 

$user = new User(); 
$user::password('secret') 
     ->username('admin') 
     ->age(40) 
     ->message('lorem ipsum');
