PHP – 错误处理

导读：foreach ($scripts as $script) { $grader = Grader::getInstance(); $grader-setApplicantId($script['applicant_id']) -setHandler($x) -doGrading();} 平地机类(Singleton类) public function setHandler($x) { $this-validateHandler($x); } public func

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

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

}

平地机类(Singleton类)

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

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

     return $this;
 }

 public function handleError($message)
 {

 }

如何编写handleError函数,使其停止当前执行意味着返回$this,在validateHandler函数中永远不会到达,将错误消息输出到屏幕,for循环却不会停止运行？

解决方法

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

        $grader->setApplicantId($script['applicant_id'])
            ->setHandler($x)
            ->doGrading();
    }
    catch ($e) {
        echo 'Grading failed for applicant '.$script['applicant_id'];
    }
}

...

public function handleError($message)
{
    throw new Exception('Unable to fruzz the bubar');
}
