PHP将XML转成数组

如果你使用 curl 获取的 xml data
$xml = simplexml_load_string($data);
$data['tk'] = json_decode(json_encode($xml),TRUE);
如果是直接获取 URL 数据的话
$xml = simplexml_load_file($data);
$data['tk'] = json_decode(json_encode($xml),TRUE);
先把 simplexml 对象转换成 json，再将 json 转换成数组。

<?php
$string = <<<XML
<?xml version='1.0'?>
<document>
 <title>Forty What?</title>
 <from>Joe</from>
 <to>Jane</to>
 <body>
  I know that's the answer -- but what's the question?
 </body>
</document>
XML;

$xml=simplexml_load_string($string);
$data = json_decode(json_encode($xml),TRUE);
var_dump( $xml );
var_dump( $data );

object(SimpleXMLElement)[1]
  public 'title' => string 'Forty What?' (length=11)
  public 'from' => string 'Joe' (length=3)
  public 'to' => string 'Jane' (length=4)
  public 'body' => string '
  I know that's the answer -- but what's the question?
 ' (length=57)
array

  'to' => string 'Jane' (length=4)
  'body' => string '
