Php 没有从工作中复制的视图

如何防止我的表中出现重复记录：

<select name="web_site">
     <?php
        $query = $db->query("SELECT * FROM `work`");
        while ($row = mysql_fetch_array($query)) {
            print '<option value="'.$row['id'].'">'.$row['title'].'</option>';
        }
    ?>
</select>

请花点时间阅读：请详细阐述你的问题

$query = $db->query("SELECT * FROM `work` group by title");

<select name="web_site">
     <?php
        $query = $db->query("SELECT DISTINCT title FROM `work`");
        while ($row = mysql_fetch_array($query)) {
            print '<option value="'.$row['id'].'">'.$row['title'].'</option>';
        }
    ?>
</select>
