Encrypting / Decrypting, passing variables values
<p>I am encrypting values of variables that I am sending through hyper link such that it is not easily editable by user..Suppose I have list of values that are shown in hyper link.</p>

<pre><code>&lt;a href="p_view.php?title=&lt;?= hash('sha512', time() + $row['p_id'])]?&gt;"&gt;&lt;?=$row['p_name'] ?&gt;&lt;/a&gt;
</code></pre>

<p>Now I want to navigate to view.php where I want to get back value of <code>$row['p_id']</code> from the title. Is their any way to do So? What are other functions that encrypt on <code>manage.php</code> and decrypt again <code>view.php</code> page?</p>
