title: PHP GET and REQUEST are not working
body: <p>I have a strange problem on a script php.</p>
  
  <p>Using a search form I have categorie and city.</p>
  
  <p>I get this using  var_dump($_REQUEST); or GET</p>
  
  <pre><code>array(4) {
      ["q"]=&gt; string(0) ""
      ["categorie"]=&gt; string(1) "2"
      ["city"]=&gt; string(1) "1"
      ["PHPSESSID"]=&gt; string(32) "81cce71a1ffe8e7793366b06e15225fc"
  }
  </code></pre>
  
  <p>on my php code I have</p>
  
  <pre><code>$Categorie = mysql_real_escape_string($_GET["categorie"]);
  $City= mysql_real_escape_string($_GET["city"]);
  </code></pre>
  
  <p>also tried REQUEST</p>
  
  <pre><code>$Categorie = mysql_real_escape_string($_REQUEST["categorie"]);
  $City= mysql_real_escape_string($_REQUEST["city"]);
  </code></pre>
  
  <p>But if I do</p>
  
  <pre><code>echo $Categorie; 
  echo $City;
  </code></pre>
  
  <p>I don't get any result.</p>
  
  <p>Is there any explanation for this?</p>
