phpstudy怎么創(chuàng)建數(shù)據(jù)庫

phpstudy數(shù)據(jù)庫創(chuàng)建步驟:

成都創(chuàng)新互聯(lián)公司成立與2013年,先為阿拉爾等服務(wù)建站,阿拉爾等地企業(yè),進(jìn)行企業(yè)商務(wù)咨詢服務(wù)。為阿拉爾企業(yè)網(wǎng)站制作PC+手機(jī)+微官網(wǎng)三網(wǎng)同步一站式服務(wù)解決您的所有建站問題。

1、點(diǎn)擊打開phpstudy軟件,然后點(diǎn)擊mySQL管理器;

2、進(jìn)入到PHPmyadmin登陸界面,默認(rèn)賬號和密碼都是root;

3、登陸進(jìn)去后,如圖所示樣式;

4、然后,點(diǎn)擊數(shù)據(jù)庫,輸入想要的數(shù)據(jù)名稱,如:new,這個隨便?。?/p>

5、點(diǎn)擊創(chuàng)建后,成功后,如圖所示;

如何實(shí)現(xiàn)PHP自動創(chuàng)建數(shù)據(jù)庫

你做好程序以后,把數(shù)據(jù)庫導(dǎo)出成sql文件

1、連接數(shù)據(jù)庫

2、讀取這個sql文件里的sql語句,并執(zhí)行

3、生成一個數(shù)據(jù)庫連接參數(shù)的php文件

?php

$con?=?mysql_connect("localhost","peter","abc123");

if?(!$con)

{

die('Could?not?connect:?'?.?mysql_error());

}

if?(mysql_query("CREATE?DATABASE?my_db",$con))

{

echo?"Database?created";

}

else

{

echo?"Error?creating?database:?"?.?mysql_error();

}

mysql_close($con);

?

?php

class?ReadSql?{

//數(shù)據(jù)庫連接

protected?$connect?=?null;

//數(shù)據(jù)庫對象

protected?$db?=?null;

//sql文件

public?$sqlFile?=?"";

//sql語句集

public?$sqlArr?=?array();

public?function?__construct($host,?$user,?$pw,?$db_name)?{

$host?=?empty($host)???C("DB_HOST")?:?$host;

$user?=?empty($user)???C("DB_USER")?:?$user;

$pw?=?empty($pw)???C("DB_PWD")?:?$pw;

$db_name?=?empty($db_name)???C("DB_NAME")?:?$db_name;

//連接數(shù)據(jù)庫

$this-connect?=?mysql_connect($host,?$user,?$pw)?or?die("Could?not?connect:?"?.?mysql_error());

$this-db?=?mysql_select_db($db_name,?$this-connect)?or?die("Yon?can?not?select?the?table:"?.?mysql_error());

}

//導(dǎo)入sql文件

public?function?Import($url)?{

$this-sqlFile?=?file_get_contents($url);

if?(!$this-sqlFile)?{

exit("打開文件錯誤");

}?else?{

$this-GetSqlArr();

if?($this-Runsql())?{

return?true;

}

}

}

//獲取sql語句數(shù)組

public?function?GetSqlArr()?{

//去除注釋

$str?=?$this-sqlFile;

$str?=?preg_replace('/--.*/i',?'',?$str);

$str?=?preg_replace('/\/\*.*\*\/(\;)?/i',?'',?$str);

//去除空格?創(chuàng)建數(shù)組

$str?=?explode(";\n",?$str);

foreach?($str?as?$v)?{

$v?=?trim($v);

if?(empty($v))?{

continue;

}?else?{

$this-sqlArr[]?=?$v;

}

}

}

//執(zhí)行sql文件

public?function?RunSql()?{

foreach?($this-sqlArr?as?$k?=?$v)?{

if?(!mysql_query($v))?{

exit("sql語句錯誤:第"?.?$k?.?"行"?.?mysql_error());

}

}

return?true;

}

}

//范例:

header("Content-type:text/html;charset=utf-8");

$sql?=?new?ReadSql("localhost",?"root",?"",?"log_db");

$rst?=?$sql-Import("./log_db.sql");

if?($rst)?{

echo?"Success!";

}

?

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sql語句就行

PHP代碼創(chuàng)建Mysql數(shù)據(jù)庫

先mysql_connect()到mysql再做mysql_query()的相關(guān)操作。

====================================================================

?php

$server = "localhost";

$username = "root";

$password = "";

$database = "myabc";

$ranks = array(

1="newbie",

2="new member",

3="member",

4="high member",

5="very high member",

6="supreme member",

7="ultra member",

8="godlike member",

9="god member",

10="low god",

11="medium god",

12="high god",

13="very high god",

14="supreme god",

15="ultra god",

16="perfect"

);

$couldNotOpenDatabase = "Could not open databaseBR\n please check your settings in config.php";

$couldNotConnectMysql="Could not connect Mysql!";

$conn=mysql_connect($server,$username,$password) or die ($couldNotConnectMysql);

if (mysql_select_db($database,$conn))

{//數(shù)據(jù)庫存在,做相應(yīng)操作

}

else

{//數(shù)據(jù)庫不存在,創(chuàng)建一個,并做相應(yīng)操作

$query = "CREATE DATABASE $database";

$result = mysql_query($query);

mysql_select_db($database,$conn)or die ($couldNotOpenDatabase);

}

?
