PHP将xml转换为json

<?php

//第一种办法：

$url = "https://api.map.baidu.com/telematics/v2/distance?waypoints=116.551016,39.915544;116.605777,39.914824&ak=1a3cde429f38434f1811a75e1a90310c";

$result = httpGet($url);

return $result;

//第二种方法：

$data_xml = file_get_contents($url);

$dom = new DomDocument;

$dom->loadXML($data_xml);

$data_json = json_encode(simplexml_import_dom($dom));

echo $data_json;

//第三种方法：

ceshi.xml：

    <xml>

        <ToUserName><![CDATA[toUser]]></ToUserName>

        <FromUserName><![CDATA[FromUser]]></FromUserName>

        <CreateTime>123456789</CreateTime>

        <MsgType><![CDATA[event]]></MsgType>

        <Event><![CDATA[subscribe]]></Event>

    </xml>

read.php：

    //$xmldata=file_get_contents("php://input");

    $path = 'ceshi.xml';

    $xml = simplexml_load_file($path);

    $data = [];

    foreach($xml->children() as $key=>$value){

        $data[(string)$key] = (string)$value;

    }

    dump($data);die;

//第四种方法：

$path = '<xml>

         <ToUserName><![CDATA[toUser]]></ToUserName>

         <FromUserName><![CDATA[FromUser]]></FromUserName>

         <CreateTime>123456789</CreateTime>

         <MsgType><![CDATA[event]]></MsgType>

         <Event><![CDATA[subscribe]]></Event>

         </xml>';

$xml = simplexml_load_string($path);

$data = [];

foreach($xml->children() as $key=>$value){

$data[(string)$key] = (string)$value;

}

dump($data);die;
