title: Multiple select option into a PHP array
body: <p>I have a selectbox list. Is it possible to select multiple options?</p>
  <pre><code>&lt;select name=&quot;access_list[ ]&quot; size=&quot;7&quot; multiple=&quot;multiple&quot;&gt;
      &lt;?php $res=mysql_query(&quot;select * from list&quot; ,$conn);
      while($row=mysql_fetch_assoc($res))
      echo&quot;&lt;option value=&quot;.$row['id'].&quot;&gt;&quot;.$row['name'].&quot;&lt;/option&gt;&quot;;?&gt;
  &lt;/select&gt;
  </code></pre>
  <p>How are the values ​that will be selected (select multiple values ​together) stored in the array?</p>
