PHP 5.4中引用的的几个问题 PHP Notice

问题 I. PHP Notice:  Only variable references should be returned by reference 
在调试函数时 

Php代码  

1. function &GetSellerList($request) {  

2.   $request->setVersion(EBAY_WSDL_VERSION);  

3.   

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

5. }  

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 

修改成: 

Php代码  

1. function &GetSellerList($request) {  

2.   $request->setVersion(EBAY_WSDL_VERSION);  

3. ‍  $res = & $this->call('GetSellerList', $request);  

4.   return ($res);  ‍

5. }  

便可. 

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 
由于PHP5.4语法改变，将245行代码 

Php代码  

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

修改成: 

Php代码  

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

便可.
