i can't understand "key=>value" this code in php?
<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>
