PHP 5.4中引用的的几个小问题

PHP 5.4中引用的的几个问题
问题 I. PHP Notice:  Only variable references should be returned by reference
在调试函数时

function &GetSellerList($request) {
  $request->setVersion(EBAY_WSDL_VERSION);

  return ($res = & $this->call('GetSellerList', $request););
}

返回错误：PHP Notice:  Only variable references should be returned by reference in /projects/ebay_api/tradding_api/EbatNsSamples/EbatNs/EbatNs_ServiceProxy.php on line 979

修改为:

function &GetSellerList($request) {
  $request->setVersion(EBAY_WSDL_VERSION);
  $res = & $this->call('GetSellerList', $request);
  return ($res);
}

即可.

问题 II. PHP Fatal error:  Call-time pass-by-reference has been removed
运行代码返回错误：[30-Jan-2013 10:51:57 UTC] PHP Fatal error:  Call-time pass-by-reference has been removed in /projects/ebay_api/tradding_api/EbatNsSamples/EbatNs/EbatNs_Client.php on line 245
因为PHP5.4语法改变，将245行代码

$this->_parser = &new EbatNs_ResponseParser( &$this, $tns, $this->_parserOptions );

修改为:

$this->_parser = &new EbatNs_ResponseParser( $this, $tns, $this->_parserOptions );

即可.
