请问大神，这样写，php的查询是否是执行了两次？
<?php<br />$act=$_GET['act'];<br />$id=$_GET['id'];<br />switch($act){<br />case "del";<br />$del=$dbc->prepare("delete from naszt where 1=1 and id=?");<br />if($del->execute(array($id))){ <br />echo "<script>";<br />echo "$(function() {";<br />echo "$('.del').click(function() {";<br />echo " $('#'+$(this).attr('id')).remove()";<br />echo "})";<br />echo "})";<br />echo "</script>";<br /> }else{<br /> echo '<script>alert("由于网络原因,删除失败,请重试!");</script>';<br /> }<br />}<br />?><br /><?php <br />$selectSpecialContent=$dbc->prepare("select * from naszt");<br />$selectSpecialContent->execute();<br />?><br /><table align="center" cellspacing="0" cellpadding="0"><br /><tr><br /><th>专题名称</th><br /><th>专题类型</th><br /><th>发表时间</th><br /><th>发表ip</th><br /><th>操作</th><br /></tr><br /><br /><?php while($row=$selectSpecialContent->fetch()){ ?><br /><tr id="<?php echo $row['id']?>"><br /><td><?php echo $row['ztname']?></td><br /><td><?php echo $row['zttype']?></td><br /><td><?php echo $row['zttime']?></td><br /><td><?php echo $row['publiship']?></td><br /><td><button><a href="ztselect.php?id=<?php echo $row['id']?>">查看</a></button><button><a href="upzt.php?act=up&id=<?php echo $row['id']?>">修改</a></button><button class='del' id="<?php echo $row['id']?>"><a href="selectzt.php?act=del&id=<?php echo $row['id']?>" >删除</a></button></td><br /></tr><br /><?php }; ?><br /></table>
