Not processing php file for highlight_file function
<p>showcode.php</p>

<pre><code>&lt;?php
$source = $file;
highlight_file( $source );
?&gt;
</code></pre>

<p>showcode.php?file=to_study.php</p>

<p>In some cases to_study.php file gets processed and I do not get the highlighted code. Error something like:</p>

<pre><code>Warning: Unterminated comment starting line 197 on line 3
</code></pre>

<p>I do not want to process the to_study.php file. I just want it to be highlighted in browser.</p>
