1. 从接口拿数据

日期

出发站

终点站

都填上

xxx/otn/leftTicketPrice/queryAllPublicPrice?leftTicketDTO.train_date=2024-06-15&leftTicketDTO.from_station=BJP&leftTicketDTO.to_station=SJP&purpose_codes=ADULT

返回的数据是这样的

{"validateMessagesShowId": "_validatorMessage","status": true,"httpstatus": 200,"data": [{"queryLeftNewDTO": {"train_no": "25000K772836","station_train_code": "K7725","start_station_telecode": "QTP","start_station_name": "秦皇岛","end_station_telecode": "HDP","end_station_name": "邯郸","from_station_telecode": "FTP","from_station_name": "北京丰台","to_station_telecode": "SJP","to_station_name": "石家庄","start_time": "05:10","arrive_time": "08:44","day_difference": "0","train_class_name": "快速","lishi": "03:34","control_train_day": "","start_train_date": "","seat_feature": "","yp_ex": "","train_seat_feature": "","infoAll_list": "1004150000#3009550001#3009250002#3008750003#1004150000#","yz_price": "00415","yw_price": "00955"},"buttonTextInfo": ""}],"messages": [],"validateMessages": {}
}

2. 解析票价

$t = [];
// 这里需要循环处理
$e = "I026500001#I023500003#J021600001#J019800002#J018500003#O008700000#O008700000#"; // 替换为你的字符串
$n = explode("#", $e);foreach ($n as $i) {if ($i) {$a = substr($i, 0, 1);$o = strlen($i) >= 10 && $i[9] === '0' ? '' : $i[9];$s = round((int)substr($i, 1, 5) / 10, 2); // Assuming you want to round to 2 decimal places, adjust as needed$t[$a . $o] = $s;if ($o !== '') {$t[$a] = $s;}}
}dd($t);
function dd($data) {print_r($data);die();
}

运行出来的结果

封装一下

3. 与标准座位比较
