我可以简化这个PHP表达式吗？

Question

I have the following PHP Function that I want to simplify, What is the best and most efficient way?

  function XMLToObject($dirtyXML) {
        $clean_xml = str_ireplace([
            'SOAP-ENV:',
            'SOAP:'
                ], '', $dirtyXML);

      $clean_xml2 = str_ireplace([
            'common:',
            ''
                ], '', $clean_xml);

      $clean_xml3 = str_ireplace([
            'pdt:',
            ''
                ], '', $clean_xml2);
        $clean_xml4 = str_ireplace([
            'apd:',
            ''
                ], '', $clean_xml3);

        $clean_xml5 = str_ireplace([
            'bs7666:',
            ''
                ], '', $clean_xml4);

        $xml = simplexml_load_string($clean_xml5);

        return $xml;
    }

I was thinking of using another function like...

function replace($oldVal,$newVal)

Then iterate over this 4 times with my different value pairs?

You can join all occurences to replace into one array:

function XMLToObject($in) {
    $find = array('SOAP-ENV:', 'SOAP', 'common:', 'pdt:', 'apd:', 'bs7666:');
    $replace = '';
    return simplexml_load_string(str_ireplace($find, $replace, $in));
}

Also, there is little value in replacing the empty string with empty string...
