I load it with

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

I tried most info from here link

But without success. I want to create some array, then i will customize it. Also i tried xml_parse_into_struct(), again without success.

Answer 1

from http://php.net/ref.simplexml:

function xml2array ( $xmlObject, $out = array () )
{
    foreach ( (array) $xmlObject as $index => $node )
            $out[$index] = ( is_object ( $node ) || is_array ( $node ) ) ? xml2array ( $node ) : $node;

    return $out;
}
