如何从php xpath获取数组？

Question

I have a var_dump($v) like this:

 object(SimpleXMLElement)#2 (3) {
    ["@attributes"]=>
    array(1) {
      ["class"]=>
      string(6) "ff_row"
    }
    ["span"]=>
    array(3) {
      [0]=>
      string(6) "aaa"
      [1]=>
      string(9) "bbb"
      [2]=>
      string(6) "ccc"
    }
    }
  }

How can I create the array of：

array(3) {
          [0]=>
          string(6) "aaa"
          [1]=>
          string(9) "bbb"
          [2]=>
          string(6) "ccc"
        }

I tried $r = $v['span'] to create the array, but it doesn't work.

Answer 1

Try...

$v = (array) $v;
$r = $v['span'];
