Can't change cookie value (php)
<p>I'm setting a cookie like so:</p>

<pre><code>setcookie ('myletter', "a", time()+60*60*24*1000, "/", ".me.com" ); 
</code></pre>

<p>Then I want to change the value so I do:</p>

<pre><code>$_COOKIE['myletter'] = "b"
</code></pre>

<p>But the old values remains. I also tried using setcookie again, that failed too</p>

<pre><code>setcookie ('myletter', "b", time()+60*60*24*1000, "/", ".me.com" ); 
</code></pre>

<p>Is there a reliable way I can actually change the value of an existing cookie?</p>
