title: PHP $_REQUEST as array
body: <p>I have a search form, I want to $_REQUEST the search terms as an array so I can list each search term out, wrapping each term in a span for styling. How do I do that?</p>
  
  <p>Edit: Here's the code requested.</p>
  
  <pre><code>&lt;form action="http://localhost/wordpress" id="search" method="get"&gt;
  &lt;input type="text" size="30" id="s" name="s" value="Type and hit enter" onfocus="javascript:this.value='';" onblur="javascript:this.value='Type and hit enter';"/&gt;
  &lt;br/&gt;
  &lt;input type="submit" value="Search"/&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Update: Thanks guys for the responses. I'll use explode, it seems fairly straightforward. Plus the name sounds cool ^^</p>
