这是个什么错误啊，怎么解决。谢谢

下面是 第14 15 16行代码
$fp_2 = fopen($filename, "r");
$file_content = fread($fp_2, filesize($filename));
fclose($fp_2);

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="Pragma" content="no-cache" />这个是14行
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {

这里写的是fwrite():
，你提供的代码中没有啊，你将fwrite的代码贴出来。
警告中的行数，不一定是源代码中的行数。

看看是不是浏览器的问题换个浏览器试试
