Best PHP xml2array function

Question

I need a function that takes a string as XML input and change that into an array. Example:

<a>
 <b>
  <c></c>
 </b>
</a>

So I can read it in PHP like this:

$array = xml2array($xmlcode);
echo $array['a']['b']['c'];

Note: I tried all xml2array functions in PHP's documentation on xml_parse, and they all didn't work or had problems.

Answer 1

You can do something very similar ($xml->a->b->c) with SimpleXML.

See the basic usage examples.

EDIT (see comments):

You can do, for the first entry:

echo $xml->entry[0]->details;

or, for every entry:

foreach ($xml as $entry) {
    echo $entry->details;
}

Answer 2

Do you need an array, or would objects be sufficient?

$root = new SimpleXMLElement($xmlcode);

echo $root->b->c;
