Is it possible to pass a value to the parameter of a function in PHP?
<p>There is a <code>function</code> which returns a value : </p>

<pre><code>function f($criteria, $extra_return)
{
   return $criteria['activity_code'];
}
</code></pre>

<p>I want to set a value to the $extra_return <code>parameter</code>. Is that possible in <code>PHP</code> ?</p>
