Php get the value from a particular node in XML

I have a xml response which has the following nodes in it

$response = '<packet version="1.6.6.0">
  <webspace>
    <del>
      <result>
        <status>ok</status>
        <filter-id>14</filter-id>
        <id>14</id>
      </result>
    </del>
  </webspace>
</packet>';

I want to grab the value of the node <filter-id> in a variable.

I am doing the following,

$dbres = simplexml_load_string($response);
$filterid = $dbres->webspace->result->filter-id;
echo $filterid;

I am getting error unexpected T_OBJECT_OPERATOR which I think indicated the hyphen "-" in filter-id. I cannot change the xml as it is a response from API. How can I get the filter-id ?

You can try this:

$dbres->webspace->result->{'filter-id'};

Use brackets:

$dbres = simplexml_load_string($response);
$filterid = $dbres->webspace->result->{filter-id};
echo $filterid;

Or cast it:

$dbres = simplexml_load_string($response);
$filterid = ((array) $dbres->webspace->result)['filter-id'];
echo $filterid;

Or - a bit weird:

$dbres = simplexml_load_string(str_replace("filter-id", "filterid", $response));
$filterid = $dbres->webspace->result->filterid;
echo $filterid;
