title: Can't echo $_GET
body: <p>I have a very very strange effect. ($_GET["var"] contains "testvalue")</p>
  
  <p>My Code:</p>
  
  <pre><code>$_POST["var"] = $_GET["var"];
  $test = $_GET["var"];
  
  echo "&lt;p&gt;post: ".$_POST["var"]."&lt;/p&gt;";
  echo "&lt;p&gt;test: ".$test."&lt;/p&gt;";
  echo "&lt;p&gt;get: ".$_GET["var"]."&lt;/p&gt;";
  </code></pre>
  
  <p>The output is:</p>
  
  <pre><code>post: testvalue
  
  test: 
  
  get: 
  </code></pre>
  
  <p>Do you have any idea why the 2nd and 3rd output is not "testvalue"?</p>
