From one array, to another array

[hover]

Hi!
 
Im trying to fill $array with data from another array, $parent_array
 
I would like $array to look like:
 

stdClass Object
(
[1] => stdClass Object
(
[titel] => Hero1
[info] =>
[href] => http://example.com/1
)

[2] => stdClass Object
(
[titel] => Hero2
[info] => This is a test
[href] =>
)
) and so on.....

$parent_array is a DOMElement Obejct and a DOMAttr Object and look like:
 

Array
(
[0] => DOMElement Object
(
[tagName] => span
[schemaTypeInfo] =>
[nodeName] => span
[nodeValue] => Hero1
[nodeType] => 1
[parentNode] => (object value omitted)
[childNodes] => (object value omitted)
[firstChild] => (object value omitted)
[lastChild] => (object value omitted)
[previousSibling] => (object value omitted)
[nextSibling] => (object value omitted)
[attributes] => (object value omitted)
[ownerDocument] => (object value omitted)
[namespaceURI] =>
[prefix] =>
[localName] => span
[baseURI] =>
[textContent] => Hero1
)

[1] => DOMElement Object
(
[tagName] => div
[schemaTypeInfo] =>
[nodeName] => div
[nodeValue] => 
[nodeType] => 1
[parentNode] => (object value omitted)
[childNodes] => (object value omitted)
[firstChild] => (object value omitted)
[lastChild] => (object value omitted)
[previousSibling] => (object value omitted)
[nextSibling] => (object value omitted)
[attributes] => (object value omitted)
[ownerDocument] => (object value omitted)
[namespaceURI] =>
[prefix] =>
[localName] => div
[baseURI] =>
[textContent] => 
)
[2] => DOMAttr Object

(
[name] => href
[specified] => 1
[value] => http://example.com/1
[ownerElement] => (object value omitted)
[schemaTypeInfo] =>
[nodeName] => href
[nodeValue] => http://example.com/1
[nodeType] => 2
[parentNode] => (object value omitted)
[childNodes] => (object value omitted)
[firstChild] => (object value omitted)
[lastChild] => (object value omitted)
[previousSibling] => (object value omitted)
[nextSibling] => (object value omitted)
[attributes] =>
[ownerDocument] => (object value omitted)
[namespaceURI] =>
[prefix] =>
[localName] => href
[baseURI] =>
[textContent] => http://example.com/1
)

Currently i can achieve the following:
 

stdClass Object
(
[0] => stdClass Object
(
[titel] => Hero1
)

[1] => stdClass Object
(
[info] => 
)

[2] => stdClass Object
(
[href] => http://example.com/1
)
 
[3] => stdClass Object
(
[titel] => Hero2
)

[4] => stdClass Object
(
[info] => This is a test
)

[5] => stdClass Object
(
[href] =>
)

 
with this code:

 

    $array = (object) array();
            foreach ($parent_array as $key => $node) {
                        $array->{$key} = (object) array();
                if (get_class($node) === 'DOMElement') {
                    if ($node->hasAttribute('class')) {
                        if ($node->getAttribute('class') === 'titel') {
                                $array->{$key}->salong = $node->nodeValue;
                        }elseif($node->getAttribute('class') === 'info'){
                                $array->{$key}->time = $node->nodeValue;
                        }
                    }
                }
                if (get_class($node) === 'DOMAttr') {
                    if ($node->nodeName === 'href') {
                            $array->{$key}->href = $node->nodeValue;
                    }
                }
                
            }

 

But as you can see, it is not multi dimensional as intended. I am not irerating over $parent_array into $array the right way.
