在类：调用函数与函数

Question

当我使用下面的代码，我得到这个错误：

Fatal error: Call to undefined function passwordHash() in 
C:\(...)\index.php on line 38 

如果我做的东西$ =新accountcreation;

并通过$ somethingn-> passwordHash（）调用它，我可以调用该函数。

但是，如何从课堂内部以我想要的方式调用函数？ （见函数：callMethods（）;）

谢谢。

class accountcreation { 

    function __construct($passwordCreation, $userCreation, 
       $ipCreation, $emailCreation, $con) { 
     $this->passwordCreation = $passwordCreation; 
     $this->userCreation = $userCreation; 
     $this->ipCreation = $ipCreation; 
     $this->emailCreation = $emailCreation; 
     $this->con = $con; 

    } 

    function callMethods() { 
     passwordHash(); 
    } 

    function passwordHash(){ 
     $this->passwordCreation = 
       password_hash($this->passwordCreation, PASSWORD_BCRYPT); 
     var_dump($this->passwordCreation); 
    } 
}

$this->passwordHash()怎么样？ :)与C++相比，您总是必须明确指定this/$this。
