获取“包含文件执行结果”的字符串
为描述问题,下面给出一简单模型:
比如有一文件 a.php,内容如下:

<br />
<div id='top'><br />
    <?php $user="张三"; ?><br />
    <p>欢迎你:<?php print $user ?> <a href='../public/logout.php'>注销</a></p><br />
</div>


有另一文件 b.php
<br />
<?php<br />
$s=file_get_contents('a.php',1);<br />
?><br />


在 b.php 中虽然能读取文件 a.php 的内容,却不是执行后的内容,若希望能解释 php 中的代码,使 $s 得到如下的结果,有什么好的办法吗?
<br />
<div id='top'><br />
    <p>欢迎你:张三 <a href='../public/logout.php'>注销</a></p><br />
</div>
