How can I convert an array to a SimpleXML object in PHP?
function array2xml(array $data, SimpleXMLElement $object = null, $oldNodeName = 'item')
{
if (is_null($object)) $object = new SimpleXMLElement(' ');
$isNumbered = true;
$idx = 0;
foreach ($data as $key => $x)
if (is_string($key) || ($idx++ != $key + 0))
$isNumbered = false;
foreach ($data as $key => $value)
{
$attribute = preg_match('/^[0-9]/', $key . '') ? $key : null;
$key = (is_string($key) && !preg_match('/^[0-9]/', $key . '')) ? $key : preg_replace('/s$/', '', $oldNodeName);
if (is_array($value))
{
$new_object = $object->addChild($key);
if (!$isNumbered && !is_null($attribute)) $new_object->addAttribute('id', $attribute);
array2xml($value, $new_object, $key);
}
else
{
if (is_bool($value)) $value = $value ? 'true' : 'false';
$node = $object->addChild($key, htmlspecialchars($value));
if (!$isNumbered && !is_null($attribute) && !isset($node->attributes()->id))
$node->addAttribute('id', $attribute);
}
}
return $object;
}
This function returns for example a list of
Input:
array(
'people' => array(
'dog',
'cat',
'life' => array(
'gum',
'shoe',
),
'fish',
),
array('yeah'),
)
Output:
dog
cat
gum
shoe
fish
yeah
This should satisfy all common needs. Maybe you may change the 3rd line to:
$key = is_string($key) ? $key : $oldNodeName . '_' . $key;
or if you are working with plurals ending with s:
$key = is_string($key) ? $key : preg_replace('/s$/', '', $oldNodeName);
