PHP 清空 MysqL 指定数据表中的所有数据，在小编在网上闲逛时，这是某技术博客的一篇文章，说是文章，并没有文字，只有代码，经过测试可以使用，现在分享给大家。
共有三个文件，其实也可以合并写成一个。
1.conn.PHP：
<?PHP
$id=MysqL_connect("localhost","root","MysqL") or die('连接失败:' . MysqL_error());
if(MysqL_select_db("PHPjcdb",$id)) //说明：PHPjcdb 是数据库名称
echo "";
else
echo ('数据库选择失败:' . MysqL_error());
MysqL_query("set names gb2312"); //设置为简体中文
?>
$id=MysqL_connect("localhost","root","MysqL") or die('连接失败:' . MysqL_error());
if(MysqL_select_db("PHPjcdb",$id)) //说明：PHPjcdb 是数据库名称
echo "";
else
echo ('数据库选择失败:' . MysqL_error());
MysqL_query("set names gb2312"); //设置为简体中文
?>
2.index.PHP：
<?PHP
include("conn.PHP");
?>
