如何在最后按下按钮下载所选文件

Question

该表显示了使用dl按钮完美的一切，但是当我点击它时没有任何反应。检查元素时，它只检测到htm代码中的部分文件名，但是在表上它看起来是完整的。

<?php

              $dirArray[]=$entryName;

            // Finds extensions of files
            function findexts ($filename) {
              $filename=strtolower($filename);
              $exts=split("[/\\.]", $filename);
              $n=count($exts)-1;
              $exts=$exts[$n];
              return $exts;
