PHP 批量删除 sql语句

首先要了解sql语句
$SQL="delete from `3water` where id in (1,2,4)";
表单大概是：

<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

$ID_Dele= implode(",",$_POST['ID_Dele']); 
$SQL="delete from `user` where id in ($ID_Dele)";
