Absolute url path with php is redirecting to 404 error
<p>I would like to know how not to redirect 404 error page when I am trying to give an absolute path with php extension. But in other extensions, it's all opening good.</p>

<p>There might be a good chance that in .htaccess files, somehow php linked with 404 error. </p>

<p>But I don't how to do it.</p>

<blockquote>
  <p>As an example:</p>

<pre><code>http://www.demotest.com/test/test.php (this link redirect me to 404 error page)

http://www.demotest.com/test/test.js (open fine, no redirect to 404 error)
http://www.demotest.com/test/test.css (open fine, no redirect to 404 error)
http://www.demotest.com/test/image1.jpg  (all media files are also open fine, no redirect to 404 error)
</code></pre>

<p>But that php is redirecting to 404 error. How to stop it to redirect. I want it to show the blank page if nothing is there in PHP code. But right now it's not happening. So need your help on this.</p>
