How to convert xml into array in php?

Question

I want to convert below XML to PHP array. Any suggestions on how I can do this?

Answer 1

Surprised no one mentioned xml_parse_into_struct:

$simple = "simple note";
$p = xml_parser_create();
xml_parse_into_struct($p, $simple, $vals, $index);
xml_parser_free($p);
echo "Index array\n";
print_r($index);
echo "\nVals array\n";
print_r($vals);
