how to reset GET variables
<p>Please pardon my PHP noobness! I want a single page to display a particular navigation based on the incoming link. It's set up as follows:</p>

<p>page1.php list item: </p>

<pre><code>&lt;li&gt;&lt;a &lt;?php if (strpos($_SERVER['PHP_SELF'], 'wood-species.php')) echo 'class="current"';?&gt;href="wood-species.php?name=standard"&gt;Wood Species&lt;/a&gt;&lt;/li&gt;
</code></pre>

<p>page2.php list item:</p>

<pre><code>&lt;li&gt;&lt;a &lt;?php if (strpos($_SERVER['PHP_SELF'], 'wood-species.php')) echo 'class="current"';?&gt;href="wood-species.php?name=premium"&gt;Wood Species&lt;/a&gt;&lt;/li&gt;
</code></pre>

<p>So the first link will set the name variable to "standard" using the GET method, and the second link will set it to "premium".  So what I want to happen is that 'wood-species.php' displays with the appropriate navigation, but I'm not sure how to destroy or unset the 'name' variable.</p>

<p>Here's what I tried to use, obviously not getting it done...</p>

<pre><code> &lt;?php

    $woodclass = $_GET['name'];
    if($woodclass="premium") {
    require("includes/premium-wide-navigation.php"); 
    echo"premium";
    clearit();
    }

    else if($woodclass="standard") {
    require("includes/standard-wide-navigation.php");
    echo"standard";
    clearit();
    }
    else {
    //
    }

    function clearit () {
    unset($GLOBALS['woodclass']);
    }

?&gt;
</code></pre>
