How to generate array from xml?

Question

PHP

Hello!
There is XML

<category categories_id="62">
     <categories_name>One</categories_name>
     <categories_id>62</categories_id>
     <parent_id>0</parent_id>
</category>
<category categories_id="652">
      <categories_name>Two</categories_name>
      <categories_id>652</categories_id>
      <parent_id>62</parent_id>
</category>
<category categories_id="581">
      <categories_name>Three</categories_name>
      <categories_id>581</categories_id>
      <parent_id>652</parent_id>
</category>
<category categories_id="581">
      <categories_name>Three</categories_name>
      <categories_id>581</categories_id>
      <parent_id>652</parent_id>
</category><category categories_id="63">
     <categories_name>One</categories_name>
     <categories_id>63</categories_id>
     <parent_id>0</parent_id>
</category>
<category categories_id="653">
      <categories_name>Two</categories_name>
      <categories_id>653</categories_id>
      <parent_id>63</parent_id>
</category>
<category categories_id="583">
      <categories_name>Three</categories_name>
      <categories_id>583</categories_id>
      <parent_id>653</parent_id>
</category>

To get
$a= [
'583'=>[
0=>'Three',
1=>'Two,
2=>'One'
],
'581'=>[
0=>'Three',
1= >'Two,
2=>'One'
],
];
The question is exactly how to collect an array of categories and subcategories, not how to process xml

Answer 1

$xml = simplexml_load_string($xml_string);
$json = json_encode($xml);
$array = json_decode($json,TRUE);

json_decode($json,TRUE);
TRUE output yields an array that can be
iterated over foreach($data as $data_1){
foreach($data_1 as $data_2){
$data_2 = ($data_2[key][key][value]);
}
}
