一个难以理解的现象

a.php的代码片段：

复制PHP内容到剪贴板

PHP代码:

<title><?php echo $title.'-某某网站口号！'; ?> </title>

与
b.php的代码片段：

复制PHP内容到剪贴板

PHP代码:

<title><?php echo $title; ?> -某某网站口号！</title>

这两段代码有什么区别呢，会导致下面这个奇怪的现象：
1. a.php在FireFox和IE7上都显示正常
2. b.php则是：
在firefox上包含该代码的页面显示正常
在IE7上包含该代码的页面显示空白页面，但查看页面源代码，却是正常的，也就是说，仅仅是IE7没有把给页面渲染出来而已
这里给出我的问题演示代码：

IE7NoDisplayIssue.zip (883 Bytes)

想来想去不得其解，不知道大家有没有遇到过类似问题呢？

注意网页编码放在 title前面

通常出现这样是你的网页编码是utf-8
而中文出现在编码前导致浏览器不能识别编码
