封装了一个验证类

    public static function each($regulations,$params) {
        //$regulations = [
        //    'name' => [
        //        'required' => '请先写姓名|10001',
        //    ],
        //    'telephone' => [

        //    ],
        //    'department_id' => [
        //        'required' => '请选择科室|10001',
        //    ],
        //    'uid' => [
        //        'required' => '缺少用户id|10001',
        //    ],
        //];
        $json = new Json();
        foreach ($regulations as $param => $regulation) {
            foreach ($regulation as $rule => $tips) {
                if (((string)$rule === 'required') && !$params[$param]) {
                    $tips = explode('|',$tips);
                    $json->printOutError($tips[0],$tips[1] ?:'10001');
                    break;
                }

                if (((string)$rule === 'telephone') && !Verify::checkMobile($params[$param])) {
                    $tips = explode('|',$tips);
                    $json->printOutError($tips[0],$tips[1] ?:'10001');
                    break;
                }

                if (((string)$rule === 'id_card') && !Verify::checkIDCard($params[$param])) {
                    $tips = explode('|',$tips);
                    $json->printOutError($tips[0],$tips[1] ?:'10001');
                    break;
                }
            }
        }

        return true;
    }
}

使用如下，

$regulations = [
    'name' => [
        'required' => '请填写姓名|10001',
    ],
    'telephone' => [
        'required' => '请填写手机号|10001',
        'telephone' => '请填写正确的手机号|10002',
    ],
    'id_number' => [
        'required' => '请填写身份证号|10001',
        'id_card' => '请填写正确的身份证号|10001',
    ],
    'department_id' => [
        'required' => '请选择科室|10001',
    ],
    'uid' => [
        'required' => '缺少用户id|10001',
    ],
];
$params = $_POST;
ValidUtil::each($regulations,$params);

通用的验证，就交给它。
跟数据库交互的验证，在下面的步骤中，继续进行。
