                    echo $result;

            ?>

这基本上是一个 EAN API 调用。现在我在同一页面上有一个按价格排序的锚标记 ，当用户单击该链接时，需要再次调用此 Web 服务，但过滤器参数不同。将对这个字符串进行一些更改。

$filter='&city='.$city.'&stateProvinceCode='.$state.'&countryCode='.$country.'&supplierCacheTolerance=MED_ENHANCED&arrivalDate='.$CheckInDate.'&departureDate='.$CheckOutDate;

所以我的问题是，当单击锚按钮时，如何通过更改 Web 服务的 URL 再次调用 php 代码。
