本文介绍如何使用php函数解析xml数据为数组。
<?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
