title: phpinfo() in query_string clear $_GET variables
body: <p>Hi im trying to make a form with a textbox to search words and functions.</p>
  
  <p>but when i search phpinfo( or phpinfo() all $_GET variables are empty.
  for example</p>
  
  <pre><code>&lt;form name="search-form" method="GET" action"results.php"&gt;
  &lt;input name="search-input" value = "" type="text"/&gt;
  &lt;input name="search-submit" value ="Submit" type="submit"/&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>if i search anything and print</p>
  
  <pre><code>print_r($_GET);
  </code></pre>
  
  <p>works
  but when i search phpinfo( or phpinfo()
  and i print with print_r($_GET) returns array() all the times.</p>
  
  <p>why is this happen?</p>
