TP5/6验证器验证身份号(使用自定义验证规则)

验证器代码：

protected $rule = [
        \'idcard|身份证\'      => \'require|checkIdCard\',
    ];

    protected $message = [
        \'idcard.require\'        => \'身份证必须填写\',
        \'idcard.checkIdCard\'    => \'身份证格式有误\',
    ];

    protected $scene = [
        \'edit\' => [
            \'idcard\'
        ],
    ];

    //验证身份证
    public function checkIdCard($idcard) {
        if(empty($idcard)){
            return false;
        }else{
            $idcard = strtoupper($idcard); # 如果是小写x,转化为大写X
            if(strlen($idcard) != 18 && strlen($idcard) != 15){
                return false;
            }
            # 如果是15位身份证，则转化为18位
            if(strlen($idcard) == 15){
                # 如果身份证顺序码是996 997 998 999，这些是为百岁以上老人的特殊编码
                if (array_search(substr($idcard, 12, 3), array(\'996\', \'997\', \'998\', \'999\')) !== false) {
                    $idcard = substr($idcard, 0, 6) . \'18\' . substr($idcard, 6, 9);
                } else {
                    $idcard = substr($idcard, 0, 6) . \'19\' . substr($idcard, 6, 9);
                }
                # 加权因子
                $factor = array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2);
                # 校验码对应值
                $code = array(\'1\', \'0\', \'X\', \'9\', \'8\', \'7\', \'6\', \'5\', \'4\', \'3\', \'2\');
                $checksum = 0;
                for ($i = 0; $i < strlen($idcard); $i++) {
                    $checksum += substr($idcard, $i, 1) * $factor[$i];
                }
                $idcard = $idcard . $code[$checksum % 11];
            }
            # 验证身份证开始
            $IDCardBody = substr($idcard, 0, 17); # 身份证主体
            $IDCardCode = strtoupper(substr($idcard, 17, 1)); # 身份证最后一位的验证码

            # 加权因子
            $factor = array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2);
            # 校验码对应值
            $code = array(\'1\', \'0\', \'X\', \'9\', \'8\', \'7\', \'6\', \'5\', \'4\', \'3\', \'2\');
            $checksum = 0;
            for ($i = 0; $i < strlen($IDCardBody); $i++) {
                $checksum += substr($IDCardBody, $i, 1) * $factor[$i];
            }
            $validateIdcard = $code[$checksum % 11];    # 判断身份证是否合理
            if($validateIdcard != $IDCardCode){
                return false;
            }else{
                return true;
            }
        }
    }

调用验证：

$post_data = input(\'post.\');

$validate = new UserValidate();
if(!$validate->scene(\'edit\')->check($post_data)){
    $this->error($validate->getError());
}

返回结果：

{\"code\":0,\"msg\":\"身份证格式有误\",\"time\":\"1689091502\",\"data\":null}
