isolating part of a url with php
<p>If I have the following url:</p>

<pre><code>http://URL/products/38/293/bannana_cake/
</code></pre>

<p>or</p>

<pre><code>htp://URL/products/38/293/fruit_cake/
</code></pre>

<p>How can I isolate just <code>bannana_cake</code> and <code>fruit_cake</code> from the examples above?</p>
