2.做删除处理页面

<?php
$ck = $_POST["ck"];

include("../toupiao/PPO.class.php");
$db = new PPO();

//第一种方式
/*foreach($ck as $v)
{
    $sql = "delete from nation where code=‘{$v}‘";
    $db->Query($sql,0);
}*/

//第二种方式
//in (‘‘,‘‘,‘‘,‘‘,‘‘)
$str = implode("‘,‘",$ck);

$str = "(‘{$str}‘)"; 

$sql = "delete from nation where code in {$str}";
$db->Query($sql,0);

header("location:piliangshanchu.php");
