$_POST['id'] php?id= not working : <p>As I understand a php POST method can be passed through the url</p>

<p>File name: test.php</p>

<pre><code>&lt;?php

if(isset($_POST['id']{
     echo'Great';
}else{
     echo'Why ?';
 }

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

<p>When I put manually in the browser /test.php?id=value it always returns the else statement</p>

<p>Why ?</p>
