已弃用：调用时传递引用已被弃用，需要建议 [重复]

Question

我有一些在在线购物车中使用的 PHP 代码我的问题是，当我尝试运行该页面时，它似乎在大多数情况下都可以正常工作，只是页面没有显示总金额（运费加上产品成本），而是显示一条错误消息，上面写着

已弃用：调用时传递引用已在 //index2.php 第 230 行

我的完整 index.php 文件如下所示

这行代码：

$fp = @fsockopen ($url, 80, &$errno, &$errstr, 30); 

请求通过引用传递$errno 和$errstr。较新版本的 PHP 要求函数的定义定义哪些参数通过引用传递，并且不赞成让调用者这样做。 fsockopen 已经将这些参数定义为传递引用，因此要修复它，请删除 &s:

$fp = @fsockopen ($url, 80, $errno, $errstr, 30);
