首先要了解sql语句

$SQL="delete from `jb51` where id in (1,2,4)";

表单大概是：

复制代码 代码如下:

<form action="" method="post">

<input name="ID_Dele[]" type="checkbox" id="ID_Dele[]" value="1"/>

<input name="ID_Dele[]" type="checkbox" id="ID_Dele[]" value="2"/>

<input name="ID_Dele[]" type="checkbox" id="ID_Dele[]" value="3"/>

<input name="ID_Dele[]" type="checkbox" id="ID_Dele[]" value="4"/>

<input type="submit"/>

</form>

php函数主要用到implode

复制代码 代码如下:

$ID_Dele= implode(",",$_POST['ID_Dele']);

$SQL="delete from `user` where id in ($ID_Dele)";
