通过PHP调用天市数据的火车查询接口

前置条件 
在开始前，请作如下准备 
1.学会用PHP输出“Hello World” 
2.去 天市数据 申请火车查询专用的KEY

操作步骤 
1.配置好PHP开发环境 
2.新建一个index.php文件，并输入以下内容：

<?phprequire_once 'curl.func.php';$appkey = 'your_appkey_here';//你在天市申请的appkey$start = '杭州';//utf8$end = '北京';//utf8$ishigh = 0;$url = "http://http://apis.tiisi.com/train/line?appkey=$appkey&start=$start&end=$end&ishigh=$ishigh";$result = curlOpen($url);$jsonarr = json_decode($result, true);//exit(var_dump($jsonarr));if($jsonarr['status'] != 0){    echo $jsonarr['msg'];    exit();}foreach($jsonarr['result'] as $val){    echo $val['trainno'].' '.$val['type'].' '.$val['station'].' '.$val['endstation'].' '.$val['departuretime'].' '.$val['arrivaltime'].'<br>';  }

3.打开浏览器，访问http://localhost/index.php，正常情况下你应该看到类似下面的内容：

{    "status": "0",    "msg": "ok",    "result": [        {            "trainno": "G34",            "type": "高铁",            "station": "杭州东",            "endstation": "北京南",            "departuretime": "07:18",            "arrivaltime": "13:07",            "sequenceno": "1",            "costtime": "5时49分",            "distance": "1279",            "isend": "1",            "pricesw": "",            "pricetd": "",            "pricegr1": "",            "pricegr2": "",            "pricerw1": "0.0",            "pricerw2": "0.0",            "priceyw1": "0.0",            "priceyw2": "0.0",            "priceyw3": "0.0",            "priceyd": "907.0",            "priceed": "538.5"        },        {            "trainno": "G32",            "type": "高铁",            "station": "杭州东",            "endstation": "北京南",            "departuretime": "08:30",            "arrivaltime": "13:28",            "sequenceno": "1",            "costtime": "4时58分",            "distance": "1279",            "isend": "1",            "pricesw": "",            "pricetd": "",            "pricegr1": "",            "pricegr2": "",            "pricerw1": "0.0",            "pricerw2": "0.0",            "priceyw1": "0.0",            "priceyw2": "0.0",            "priceyw3": "0.0",            "priceyd": "907.0",            "priceed": "538.5"        }    ]}
