Question

foreach ($scripts as $script) {    
    $grader = Grader::getInstance();

    $grader->setApplicantId($script['applicant_id'])
        ->setHandler($x)
        ->doGrading();

}

Grader Class (Singleton class)

 public function setHandler($x)
 {
     $this->validateHandler($x);
 }

 public function validateHandler($x)
 {
     $this->handleError("Invalid Handler");

     return $this;
 }

 public function handleError($message)
 {

 }

How to i write the handleError function such that it stops the current execution meaning return $this in the validateHandler function is never reached, prints an error message to the screen, the for loop however does not stop running?
