php怎么創(chuàng)建數(shù)據(jù)庫表

那要看你用的是什么數(shù)據(jù)庫，如果要?jiǎng)?chuàng)建成功的提示的話更簡(jiǎn)單，只需要加上一個(gè)判斷語句就好了......

怎么通過一個(gè)php文件在數(shù)據(jù)庫里建立一張表

概念混亂啊，PHP是一種編程語言，不是文件。

表是數(shù)據(jù)庫中的對(duì)象，通常應(yīng)該通過數(shù)據(jù)庫管理系統(tǒng)來建立表，然后通過編程語言做出的程序訪問表中的數(shù)據(jù)，而不是動(dòng)態(tài)建立表格。

如何在php創(chuàng)建數(shù)據(jù)庫與數(shù)據(jù)表

創(chuàng)建數(shù)據(jù)庫：create database 數(shù)據(jù)庫名

創(chuàng)建數(shù)據(jù)表：

CREATE TABLE `users` (

`id` tinyint(10) auto_increment primary key NOT NULL,

`username` varchar(30) NOT NULL,

`age` int(10) NOT NULL

) ENGINE=MyISAM DEFAULT CHARSET=utf8;

執(zhí)行這兩個(gè)sql語句就行

用php中sql建數(shù)據(jù)庫和表

下個(gè)開源免費(fèi)的數(shù)據(jù)庫mysql安裝程序 和客戶端；

然后再使用SQL建庫，或者就直接使用test數(shù)據(jù)庫

接著創(chuàng)建表、建表結(jié)構(gòu)

CREATE TABLE 的語法是：

CREATE TABLE "表格名"

("欄位 1" "欄位 1 資料種類",

"欄位 2" "欄位 2 資料種類",

... )

若我們要建立顧客表格，我們就打入以下的 SQL：

CREATE TABLE customer

(First_Name char(50),

Last_Name char(50),

Address char(50),

City char(50),

Country char(25),

Birth_Date date)

其他的SQL可以參考

建立conn.php數(shù)據(jù)庫連接,建立一個(gè)數(shù)據(jù)庫表

建立數(shù)據(jù)表，得是你在cmd窗口或者phpmyadmin、navicat

for

mysql這類終端軟件里進(jìn)行操作。建立數(shù)據(jù)表的指令是create

table

xxx

();

連接數(shù)據(jù)庫使用php封裝好的一個(gè)函數(shù)mysql_connect();

例如：

mysql_connect('127.0.0.1','root','root');

這樣的語句來連接，因?yàn)檫B接數(shù)據(jù)庫會(huì)生成連接標(biāo)識(shí)資源，你把這個(gè)資源賦給一個(gè)新變量

$active_connection_sort

=

mysql_connect('127.0.0.1','root','root');

這樣你拿著新變量去玩別的也好下手。

括號(hào)中間都是參數(shù)，第一個(gè)是連接地址，比如localhost，但我個(gè)人建議還是127.0.0.1省得還得來一步解析，第二個(gè)參數(shù)是用戶名，第三個(gè)參數(shù)是密碼，都用英文單括號(hào)括上。參數(shù)和參數(shù)之間用英文逗號(hào)間隔起來。

用框架做久了這個(gè)東西都容易忘，我也是憑記憶寫的，你試試看這個(gè)能不能過關(guān)。
