Unset all session variables with similar name
<p>I'm using some <code>$_SESSION</code> variables for filtering many query records that have a similar name (ex. <code>$_SESSION['nameFilter']</code> or <code>$_SESSION['cityFilter']</code> and so on).</p>

<p>I'm using a link for resetting these filters, but I want to know if there is a way to unset all <code>$_SESSION</code> variables that have a name that is like:</p>

<p><code>$_SESSION[(somewords)Filter]</code></p>
