Yii2 try catch exception的正确姿势

try {
	$mailer->compose()
		->setFrom($setFrom)
		->setTo($to)
		->setSubject($subject)
		->setHtmlBody($htmlBody)
		->send();
	return true;
} catch (Exception $e) {
	var_dump($e);
	Yii::$service->helper->errors->add('email send from is empty');
	return false;
}

通过上面的代码是无法获取异常的，需要将 Exception $e 改成 \Exception $e 才行

改后的代码：

try {
	$mailer->compose()
		->setFrom($setFrom)
		->setTo($to)
		->setSubject($subject)
		->setHtmlBody($htmlBody)
		->send();
	return true;
} catch (\Exception $e) {
	var_dump($e);
	Yii::$service->helper->errors->add('email send from is empty');
	return false;
}
