Prevent direct access PHP
<p>I have 2 script. That's :</p>

<ol>
<li>registration.html</li>
<li>process_registration.php</li>
</ol>

<p>Sometimes someone open the link direct into process_registration.php, so how can I prevent that ?</p>

<p>Process_registration.php function is to save the data get from input from registration.html.</p>

<p>Any idea ?</p>
