                  问题描述

                  谁能帮我解决这个问题我有一个像

                  Hi could anyone help me with this I have a URL like

                  parent/child/a=1&b=2$c=3
                  

                  然后我有一个链接可以向该 URL 添加变量

                  then I have a link that would add variable to that URL

                  <a href="<?php echo $_SERVER["REQUEST_URI"]."&d=test1";?>">LINK 1</a>
                  <a href="<?php echo $_SERVER["REQUEST_URI"]."&d=test2";?>">LINK 2</a>
                  

                  每次我点击链接时,指向 URL 的变量 d 都会像这样继续复制

                  every time I click my link the variable d to URL keep on reproducing like this

                  parent/child/a=1&b=2&c=3&d=test2&d=test2&d=test2&d=test1&d=test1
                  

                  我知道 $_SERVER["REQUEST_URI"] 不断获取当前 URL,这就是我得到该结果的原因.我已经尝试了 $_SERVER[""] 的一些属性.我喜欢的是改变 d 变量值,不知道怎么做.非常感谢任何回复.谢谢!

                  I know that the $_SERVER["REQUEST_URI"] keep getting the current URL that is why I get that result. I have tried the some of properties of $_SERVER[""]. What I like is to change the d variable value, any idea how to do it. Any response is well appreciated.Thanks!

                  $query = $_GET;
                  // replace parameter(s)
                  $query['d'] = 'new_value';
                  // rebuild url
                  $query_result = http_build_query($query);
                  // new link
                  <a href="<?php echo $_SERVER['PHP_SELF']; ?>?<?php echo $query_result; ?>">Link</a>
