使用方法：
聲明數(shù)據(jù)庫(kù)對(duì)象
$Conn = new Mysql;
加載數(shù)據(jù)庫(kù)參數(shù)
$Conn->Parameter(數(shù)據(jù)庫(kù)服務(wù)器, 數(shù)據(jù)庫(kù)用戶名, 數(shù)據(jù)庫(kù)密碼, 數(shù)據(jù)庫(kù)名稱, 數(shù)據(jù)庫(kù)編碼, 數(shù)據(jù)庫(kù)表前綴[可為空]);

上面的代碼就已經(jīng)加載這個(gè)類文件進(jìn)來了，并且初始化了一些數(shù)據(jù)庫(kù)連接參數(shù)！

下面介紹幾個(gè)基本是方法函數(shù)：
1、 $Conn -> Table();
選擇數(shù)據(jù)表，參數(shù)是數(shù)據(jù)表名稱
2、$Conn -> Field();
選擇的字段名稱，多個(gè)用逗號(hào)隔開，如不調(diào)用這個(gè)方法，則返回全部
3、$Conn -> Where();
Sql Where子語(yǔ)句，根據(jù)條件篩選
4、$Conn -> Order();
Sql 排序
5、$Conn -> Page(int);
參數(shù)是一個(gè)正整數(shù)數(shù)字，如調(diào)用這個(gè)方法，記錄將分頁(yè)顯示
6、$Conn -> Select(布爾值);
執(zhí)行查詢，返回查詢結(jié)果，如果有，則是一個(gè)二維數(shù)組，如果無，則返回假，參數(shù)可省略，如省略，默認(rèn)為真，返回的數(shù)組包含數(shù)字元素
7、$Conn -> Del();
刪除記錄
8、 $Conn -> Edit(array());
修改記錄，參數(shù)是一個(gè)一維數(shù)組，數(shù)組鍵是字段名稱，數(shù)組值是字段值
9、$Conn -> Into(array());
添加記錄，參數(shù)是一個(gè)一維數(shù)組，數(shù)組鍵是字段名稱，數(shù)組值是字段值。

以上方法可連續(xù)調(diào)用，比如：
復(fù)制代碼 代碼如下:
$Rult = $Conn -> Table('user') -> Select(); //查詢返回user表的所有記錄
$Rult = $Conn -> Table('user') -> Page(20) -> Select();//查詢返回user表的所有記錄，并分頁(yè)顯示，每頁(yè)20條；
