PHP脚本，用于动态生成当前目录中存在的PDF文件的链接

Question

我有一个php代码读取TEXT文件，并根据用户请求搜索字符串。系统在表中显示结果，该结果包含文件名和存在的行号。

每个TEXT文件在同一文件夹中将其另一个副本作为PDF文件。

我需要将TEXT文件作为PDF文件的超链接。

到目前为止，我已经成功制作了TEXT文件的超链接

我知道这条线必须有扩展但我不知道如何添加：

$filenamehtml .= "<th><a href ='".$filename."' target='_blank'>$filename</a></th>";

code:

 <?php

$result = [];
if(isset($_POST["search"]))
{
    $search =$_POST['name'];
    echo "the word  $search exist: <br><br>";
    foreach(glob($_SERVER['DOCUMENT_ROOT']."/readfiletest/*.txt") as $txts)
    {
        $line = 1;
        $temp   = [];
        $myFileLink = fopen($txts, 'r');
        while(!feof($myFileLink))
        {
            $myFileContents = fgets($myFileLink);
            if( preg_match_all('/('.preg_quote($search,'/').')/i', $myFileContents, $matches))
            {

                $temp['filename'] = basename ($txts);
                foreach($matches[1] as $match)
                {
                    $temp['lines'][] = $line;
                }
            }
            ++$line;
        }
        fclose($myFileLink);

        $result[] = $temp;
    }

    //display the table
    echo '<table border=2>';

    $filenameHtml    = '<tr>';
    $lineNumberHtml    = '<tr>';
    foreach ($result as $item){
     $filename = isset($item['filename']) ? $item['filename'] : '';
     $lines = isset($item['lines']) ? implode(',',$item['lines']) : '';
     //$filenameHtml .= "<th>$filename</th>";
     $filenameHtml .= "<th><a href ='".$filename."' target='_blank'>$filename</a></th>";
     $lineNumberHtml .= "<td>$lines</td>";
    }
    $filenameHtml    .= '</tr>';
    $lineNumberHtml  .= '</tr>';

    echo $filenameHtml.$lineNumberHtml;
    echo '</table>';
}
