下面也是自己亲自做的 simplexml_load_string 例子
function _getGuishude($tel)
{
    $tel = strval(trim($tel));
    if(empty($tel)){
        return '';
    }
    $tel = substr($tel,0,11);
    $guishudi = @file_get_contents("http://life.tenpay.com/cgi-bin/mobile/MobileQueryAttribution.cgi?chgmobile=".$tel);
    $guishudi = iconv('GBK','UTF-8',$guishudi);
    $guishudi =  str_replace('encoding="gb2312"','encoding="utf-8"',$guishudi);
    $dataObj = simplexml_load_string($guishudi);
    
    if(strval($dataObj->retmsg)=='OK'){
        $outputstring = trim(strval($dataObj->province)).'省'.trim(strval($dataObj->city)).'市  '.strval($dataObj->supplier).' ';
    }
    else{
        $outputstring = '不合法的手机号码';
