两行代码(https://www.php.net/manual/en/book.simplexml.php#113485)

$xml = new SimpleXMLElement("<your><xml><string>ok</string></xml></your>");
$array = (array)$xml;

奇怪的是没有人提到xml_parse_into_struct:

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