header('Content-type:text/html;charset=utf-8');
include 'class.juhe.wz.php'; //引入文件

二、配置参数

//接口基本信息配置
$appkey = '**********'; //您申请的违章查询key
$wz = new wz($appkey);

三 、查询违章支持的城市列表

由于支持的城市会不定期更新，但不会太频繁，大家可以将这些数据缓存，比如每3小时来更新一次，不用每次都请求接口。

$wzcitys = $wz->getCitys(); //查询所有的支持城市
$wzcitys = $wz->getCitys('GD'); //查询指定省份下的城市

返回的数据格式如下：（很重要，涉及到下一步查询违章所需的一些条件,具体的字段意思可以参考官方的接口文档，其中regist和registno 可以忽略，是旧版本才需要的）

{"resultcode": "200","reason": "成功的返回","result": [{"province": "北京","province_code": "BJ","citys": [{"city_name": "北京","city_code": "BJ","abbr": "京","engine": "1","engineno": "0","classa": "0","class": "0","classno": "0","regist": "0","registno": "0"}]}],"error_code": 0
}

四、查询车辆的违章信息

//根据需要的查询条件，查询车辆的违章信息
$city = 'GD_DG'; //城市代码，必传
$carno = '粤S*****'; //车牌号，必传
$engineno = '****'; //发动机号，需要的城市必传
$classno = '*****'; //车架号，需要的城市必传
$wzResult = $wz->query($city,$carno,$engineno,$classno);
if($wzResult['error_code'] ==0){if($wzResult['result']['lists']){foreach($wzResult['result']['lists'] as $key =>$w){//以下就是根据实际业务需求修改了echo $w['area']." ".$w['date']." ".$w['act']." ".$w['fen']." ".$w['money']."<br>";}}else{echo "该车无违章记录";}
}else{//查询不成功echo $wzResult['error_code'].":".$wzResult['reason'];
}
