php学习日志

1、php文件与数据库编码一致了,页面仍然乱码。检查后原来是 utf8与utf-8的问题。

???? mysql_connect("localhost","root","root");

???? mysql_query("set names uft-8;"); 换成 mysql_query("set names utf8");

?

2、对mysql_fetch_array、mysql_fetch_row、 mysql_fetch_assoc、mysql_fetch_object 有了基本的认识.

??? a、用mysql_fetch_array函数可以通过键名(字段名)与数字键获取值。如$row["user"]、$row[0]

??? b、mysql_fetch_row只能通过数字键获取字段值。如$row[0]

??? c、mysql_fetch_assoc则是通过$row["user"]获取值

??? d、mysql_fetch_object则是将每一行记录当成对象 每个字段相当与是 这个对象的 属性。

???????? 获取值方式 $row->user。

?

3、smarty安装不成功

???? 解压之后还需要设置config、templates等文件夹权限。
