附属标签未在链接中正确添加

Question

我正在尝试使用 php 创建附属链接 geenrator，我正在使用以下代码生成。但是只有当链接包含任何附属标签时，此代码才在链接的最后添加 affid。如果我使用此链接，则“ https://www.flipkart.com/whirlpool-1-5-ton-5-star-split-inverter-ac-white/p/itmf8fb8a675505d?pid=ACNFE6K2BXFY6EKX ”它会向我发送相同的信息链接而不添加任何标签。

任何人都可以帮我解决这个问题吗？

$url = "https://www.flipkart.com/whirlpool-1-5-ton-5-star-split-inverter-ac-white/p/itmf8fb8a675505d?pid=ACNFE6K2BXFY6EKX";

      $afftag = 'harshk'; //our affiliate ID

        $affstring = 'affid='; // url parameter for affiliate ID

        if (parse_url($url, PHP_URL_QUERY)): //check if link has query string

            if (strpos($affstring, $url) !== true) : //check if link already has affiliate ID

                $url = preg_replace("/(".$affstring.").*?(\z|&)/", "$1".$afftag."$2", $url);

        else:

                $url = $url.'&'.$affstring.$afftag;

            endif;

        else:

            $url = $url.'?'.$affstring.$afftag;

        endif;
