title: Create folder at particular path
body: <p>I'm pretty new with PHP so the question could seem easy. I have an html file with an input with these attributes:</p>
  
  <pre><code>&lt;td width="30%"&gt;
  &lt;input type="text" id="prog1" name="prog1" style="width:150px"&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>I must create a new folder on my server inside another folder called <code>wars</code> that already exists. The new folder's name is stored on that input. For example, if the input's text is "home", my PHP script is gonna make a folder here: <code>wars/home</code>.</p>
  
  <pre><code>&lt;?
  $val = $_REQUEST['prog2'];
  mkdir("/wars/".$val, 0777);
  ?&gt;
  </code></pre>
  
  <p>This is my code but it's not working because inside the main folder <code>wars</code> I can't find <code>home</code>. Do you have any suggestion?</p>
