php manually redirect to 404 error page
<p>I want to redirect any incoming user to the 404 Error Page if s/he reaches the page I don't want him/her to reach. </p>

<p>I don't want to redirect to the error page like</p>

<pre><code>header("Location: err.php?e=404");
</code></pre>

<p>Instead, it should seem like the page really doesn't exist.</p>

<p>I googled about this but all I got was about .HTACCESS Custom Error page.</p>
