$linkID=@mysql_connect("localhost","root","123456");
$db=@mysql_select_db("bean");
//echo $_POST['kk'];
//echo array('1','2','3');
foreach($_POST['kk'] as $pp)//遍历数组，给每个赋值
{
echo $pp;
$rowID=$pp;
$query="delete from member3 where id='$rowID'";//查询语句
$result=mysql_query($query);//放到数据库执行
if(!mysql_affected_rows()==0)
echo "
