PHP 批量删除数据的方法分析_php技巧
大家可以参考下面的这篇文章http://www.jb51.net/article/6488.htm
SQL:$SQL="delete from `doing` where id in ('1,2,3,4')";
数据用逗号隔开。
表单:
好$ID_Dele=$_POST['ID_Dele']将会是一个数组,虽然说PHP是弱类型的,但这里可没ASP弱。
ASP可以直接:
SQL="delete from [doing] where id in ('"&ID_Dele&"')"进行删除。但PHP不能把$ID_Dele直接放进去。因为$ID_Dele可不是'1,2,3,4'哦,因为$ID_Dele是一个数组,具有键和值。
好,PHP中也不难,刚好有个函数:implode(),对了。同split()explode()功能刚好相反的一个函数,后两者是用某字符(比如逗号)分割的,而前者则可以拼接为字符串。
因此:
$ID_Dele= implode(",",$_POST['ID_Dele']);
$SQL="delete from `doing` where id in ($ID_Dele)";
脚本之家提供测试代码:
if ($_POST["action"]="doing"){
$del_id=$_POST["ID_Dele"];
$ID_Dele= implode(",",$_POST['ID_Dele']);
echo "
