问题描述

在下面的代码中，所有内容均正常运行
我想格式化页面上显示的文本
我正在读取的文件已经格式化，如正确的缩进，间距等.
但是它不显示文件中存在的选项卡

我该怎么办?

In the below code all things are working properly
I wants to format the text displayed on my page
The file which I am reading is already formatted like proper indentation, spacing, etc.
But it is not displaying tabs that are present in file

What should I do?

<?php
          $catid = $_GET['catid'];
          $progid = $_GET['progid'];

          $con = mysql_connect("localhost","username","password");
          mysql_select_db("DB Name", $con);

          $progname = mysql_query("SELECT * FROM progs WHERE ProgId=$progid And CategoryId=$catid");
          $fnames = mysql_fetch_array($progname);

          $filename="Java/" . $fnames['ProgName'];
          $handle = fopen($filename, "r");
          $contents = fread($handle, filesize($filename));
          fclose($handle);
          $content = nl2br($contents);
          echo $content;

          mysql_close($con);
?>
