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");
