请教一个判断问题,谢谢指导
require("conn.php");
$sid=$_GET["id"];
$result=mysql_query("select * from jswo where id='$sid' order by id desc limit 0,1");
$rs=mysql_fetch_array($result);
?>
src="" width=185>
对于以上代码,现在我有个判断,假设上面IMG字段为空,没有内容,那我想实现
src="" width=185>这段代码就全部不显示,假设IMG字段有数据时,那
" width=185>这段代码就全部显示出来!请问该怎么写呀?谢谢指导!
------解决方案--------------------
echo !empty($rs["img"]) ? '
' : '';
?>
