Detailed explanation of PHP implementation of parsing xml into array case

This time I will bring you a detailed explanation of the case of PHP parsing xml into an array. What are the precautions for PHP to parse xml into an array. The following is a practical case, let's take a look.

Recently I want to make a plug-in mechanism, which requires the use of xml. When parsing xml, it needs to be converted into an array. I specially record this parsing method

xmlDemo.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<main xmlns="http://www.xiaoetongo.cn" versionCode="1.0">
<controller co="Aritles">
<meth title="测试插件" do="aritle"/>
</controller>
<controller co="Ari">
<meth title="测试插件" do="ar"/>
<meth title="测试插件" do="a"/>
</controller>
<install><![CDATA[]]></install>
<upgrade><![CDATA[]]></upgrade>
</main>

php code:

<?php
$xmls=file_get_contents("xmlDemo.xml");
$xml =simplexml_load_string($xmls);
$xmljson= json_encode($xml);
$xml=json_decode($xmljson,true);
var_dump($xml);

Run result:

array(4) {
 ["@attributes"]=>
 array(1) {
  ["versionCode"]=>
  string(3) "1.0"
 }
 ["controller"]=>
 array(2) {
  [0]=>
  array(2) {
   ["@attributes"]=>
   array(1) {
    ["co"]=>
    string(7) "Aritles"
   }
   ["meth"]=>
   array(1) {
    ["@attributes"]=>
    array(2) {
     ["title"]=>
     string(12) "测试插件"
     ["do"]=>
     string(6) "aritle"
    }
   }
  }
  [1]=>
  array(2) {
   ["@attributes"]=>
   array(1) {
    ["co"]=>
    string(3) "Ari"
   }
   ["meth"]=>
   array(2) {
    [0]=>
    array(1) {
     ["@attributes"]=>
     array(2) {
      ["title"]=>
      string(12) "测试插件"
      ["do"]=>
      string(2) "ar"
     }
    }
    [1]=>
    array(1) {
     ["@attributes"]=>
     array(2) {
      ["title"]=>
      string(12) "测试插件"
      ["do"]=>
      string(1) "a"
     }
    }
   }
  }
 }
 ["install"]=>
 array(0) {
 }
 ["upgrade"]=>
 array(0) {
 }
}
