How to convert array to SimpleXML

Question

How can I convert an array to a SimpleXML object in PHP?

Answer 1

a short one:

 'blub',
  'foo' => 'bar',
  'another_array' => array (
    'stack' => 'overflow',
  ),
);
$xml = new SimpleXMLElement('');
array_walk_recursive($test_array, array ($xml, 'addChild'));
print $xml->asXML();

results in

  bla
  foo
  stack

keys and values are swapped - you could fix that with array_flip() before the array_walk. array_walk_recursive requires PHP 5. you could use array_walk instead, but you won't get 'stack' => 'overflow' in the xml then.
