Transfer xml data in php into array form, divided into three steps

2: Convert object (Object) into json format (json_encode())

$xml = &#39;<?xml version="1.0" encoding="utf-8"?>
        <res>
            <test>test</test>
            <test1>test1</test1>
            <test2>test2</test2>
        </res>&#39;;
$xml =simplexml_load_string($xml); //xml转object
$xml= json_encode($xml);  //objecct转json
$xml=json_decode($xml,true); //json转array
echo &#39;<pre class="brush:php;toolbar:false">&#39;;
print_r($xml);

(2) Use simplexml_load_file method

$xml =simplexml_load_file('./KPP-190107-0005.xml'); //xml转object
$xml= json_encode($xml);  //objecct转json
