php with multiple list item box
<p>Its first time I am using select box for multiple values. my html code is</p>

<pre><code>&lt;select name="depend_on" size="3" multiple="multiple" class="text_field_detail" id="depend_on"  style="width:250px;"&gt;&lt;? get_service_dependent_list($x); ?&gt;&lt;/select&gt;
</code></pre>

<p>I am requesting all set of selected values. I used php script as</p>

<pre><code>    $depend_on = array();
    $depend_on[] = $_REQUEST["depend_on"];
</code></pre>

<p>$depent_on echo single last selected value. How can I retrieve all selected values from multiple select box ?</p>
