Disallow cloning in PHP?

[Vlades]

Hello,

 

Is there any way to disallow the use of "clone " for an object?

 

What I mean is, let's say I have a class named "user"

I am able to clone the object ;

$student = new user();

$teacher = clone $student;

 

Is there any keyword that does not allow me to clone the "$student" object?

 

Thank you in advance

public function __clone() {

throw new Exception( "you are not allowed to clone this object" );

}

I see, it is the only way?
Is there any keyword that locks the object and does not allow it to clone?

Make it private.

 

class IamNotDolly {
  private function __clone() {}
}
