PHP警告：＆＃34;非法字符串偏移＆＃39; @ id＆＃39;在test.php＆＃34; PHP警告：＆＃34;非法字符串偏移＆＃39;订单＆＃39;在test.php＆＃34; ...

....
$ret1=curlDest($transaction_url);
$retval = $ret1["Response"]["TransactionList"]["@TotalCount"];
foreach ($ret1["Response"]["TransactionList"]["Transaction"] as $v)
  { 
     $transaction_id       = $v["@Id"];        
     $order_id             = array();
     $orderid_query_string = '';

错误说

illegal string offset '@id'

您应该使用大写的@Id代替。
