PHP中Restful api 错误提示返回值实现思路

interface Hint {
function Error($_errors,$code);
}

class Template implements Hint{
function Error($_errors,$code) { 
if (empty($_errors)) {
print_r(json_encode([]));
} else { 
$errors['error']['name'] = 'Not Found';
$errors['error']['message'] = $_errors;
$errors['error']['error_code'] = $code; 
print_r(json_encode($errors));
}
}
}

interface createMsg { 
function Msg(); 
}

class FactoryMsg implements createMsg{
function Msg() {
return new Template;
}
}

class ErrorMsg {
// 抽象工厂里的静态方法
public static function Info($_errors) { 
$Factory = new FactoryMsg;
$result = strstr($_errors,Yii::t('yii','Not exist')); //数据不存在 20001
$result1 = strstr($_errors,Yii::t('yii','Null')); //参数不能为空 20002
$result2 = strstr($_errors,Yii::t('yii','Fail')); //新增、更新、删除失败 20003
$result3 = strstr($_errors,Yii::t('yii','Not right')); //XX不正确 20004
$result4 = strstr($_errors,Yii::t('yii','Robc')); //XX无权限 20005
//数据不存在 20001
if(!empty($result)){ 
$M = $Factory->Msg();
$M->Error($_errors,'20001');die;

//参数不能为空 20002
