cannot get the $_GET value in PHP : <p>i am passing values inthe URL by the $_GET :</p>

<pre><code> &lt;a href="http://localhost/myFiles/confirmation.php?`pseudo='.$pseudo.'&amp;key'.$key.'"&gt;Confirmer votre compte&lt;/a&gt;`
</code></pre>

<p>i get the values in the URL of the concerned page like this :</p>

<pre><code>http://localhost/myFiles/confirmation.php?pseudo=test&amp;key08656996298
</code></pre>

<pre><code>echo $_GET['pseudo'] ;
echo $_GET['key'];
</code></pre>

<p>it displays the 'pseudo' but not the key ! this is the error
