title: i can't understand "key=>value" this code in php?
body: <p>I got a question about the "$key => $value" in the code below... I looked it up in google but it didn't returned any results.. All I know is that "=>" is used in arrays like x = array('a' => 'b'). </p>
  
  <pre><code>function _stripslashes_rcurs($variable,$top = true)
      {
          $clean_data = array();
          foreach($variable as $key =&gt; $value)
          {
              $key = ($top) ? $key : stripslashes($key);
              $clean_data[$key] = (is_aray($value)) ?
                  stripslashes_rcurs($value, false) : stripslashes($value);
          }
          return $clean_data;
      }
  </code></pre>
  
  <p>thank you for your help</p>
