Automatically link words using PHP
<p>I have thousands of PHP pages which have a header and footer included using php, like</p>

<pre><code>&lt;?php include("header.php"); ?&gt; //STATIC CONTENT HERE  &lt;?php include("footer.php"); ?&gt;
</code></pre>

<p>I want to implement auto keyword linking for certain keywords in the static text. But I can only add PHP codes to my header or footer files.</p>
