XML到数组？ [PHP]

Question

Well I been having issues changing an xml back into an array....It would be simple if each xml followed the same format but every XML is different with the exception of the <Formula> tag, formulaname and movespeed ex:

<Formula>
<formulaname>Basic</formulaname>
<movespeed>1</movespeed>
<str>4</str>
<dex>3</dex>
<int>1</int>
<will>2</will>
</Formula>

or

<Formula>
<formulaname>Basic</formulaname>
<movespeed>1</movespeed>
<box>4</box>
<chicken>3</chicken>
<ducks>1</ducks>
<cereal>2</cereal>
</Formula>

What I have tried:

$xml = simplexml_load_file("test.xml");
print_r($xml);

This actually prints something but I couldn't get past that or even echo it..

foreach($xml->text as $string) { 
  print_r($string);
  echo 'attributes: '. $string->attributes() .'<br />';
}

Didn't work, originally it's for strings but none of them are strings...

foreach ($xml->Formula as $element) {
  foreach($element as $key => $val) {
   echo "{$key}: {$val}";
  }

Didn't work either, I needed something like this to work so I can use the values from the array without knowing what exactly the value will be called..

You can't access children by using a foreach on the node itself, you need to use .children():

$s =<<<EOS
<root>
<Formula>
<formulaname>Basic</formulaname>
<movespeed>1</movespeed>
<box>4</box>
<chicken>3</chicken>
<ducks>1</ducks>
<cereal>2</cereal>
</Formula>
</root>
EOS;

$xml = simplexml_load_string($s);

foreach ($xml->Formula as $element) {
    foreach($element->children() as $key => $val) {
        echo "{$key}: {$val}";
    }
}
