php 使用simplexml_load_string转换xml数据格式失败

本文介绍如何使用php函数解析xml数据为数组。

php 复制代码

<?php

$a = '<xml><ToUserName><![CDATA[ww8b77afac71336111]]></ToUserName><FromUserName><![CDATA[sys]]></FromUserName><CreateTime>1736328669</CreateTime><MsgType><![CDATA[event]]></MsgType><Event><![CDATA[change_external_contact]]></Event><ChangeType><![CDATA[del_external_contact]]></ChangeType><UserID><![CDATA[Xu]]></UserID><ExternalUserID><![CDATA[woh0dIDAAA4kq6S_aXw1UkX7_qXb22ng]]></ExternalUserID></xml>';

$xmlObject = simplexml_load_string($a,'SimpleXMLElement', LIBXML_NOBLANKS);
$json = json_encode($xmlObject);
var_dump($json);
$array = json_decode($json, true);
print_r($array);

打印后发现xml内容中带有CDATA的好像不能正常解析

string(133) "{"ToUserName":{},"FromUserName":{},"CreateTime":"1736328669","MsgType":{},"Event":{},"ChangeType":{},"UserID":{},"ExternalUserID":{}}"

Array

(

$ToUserName$ => Array

(

)

$FromUserName$ => Array

(

)

$CreateTime$ => 1736328669

$MsgType$ => Array

(

)

$Event$ => Array

(

)

$ChangeType$ => Array

(

)

$UserID$ => Array

(

)

$ExternalUserID$ => Array

(

)

)

期初我以为是这个函数有问题，随后我查阅了官方文档，https://www.php.net/manual/zh/libxml.constants.php

看起来不错，我来替换下尝试一下

string(239) "{"ToUserName":"ww8b77afac713361bd","FromUserName":"sys","CreateTime":"1736328669","MsgType":"event","Event":"change_external_contact","ChangeType":"del_external_contact","UserID":"XuBin","ExternalUserID":"woh0dIDAAA4kq6S_aXw1UkX7_qXb22ng"}"

Array

(

$ToUserName$ => ww8b77afac71336111

$FromUserName$ => sys

$CreateTime$ => 1736328669

$MsgType$ => event

$Event$ => change_external_contact

$ChangeType$ => del_external_contact

$UserID$ => Xu

$ExternalUserID$ => woh0dIDAAA4kq6S_aXw1UkX7_qXb22ng

)

完美
