php批量sql删除

$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)";
