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。

幾種常用PHP連接數(shù)據(jù)庫的代碼示例

PHP連接數(shù)據(jù)庫之PHP連接MYSQL數(shù)據(jù)庫代碼

?php? ? $mysql_server_name= localhost ;? //改成自己的mysql數(shù)據(jù)庫服務(wù)器 ? $mysql_username= root ;? //改成自己的mysql數(shù)據(jù)庫用戶名 ? $mysql_password= ;? //改成自己的mysql數(shù)據(jù)庫密碼 ? $mysql_database= mycounter ; ?//改成自己的mysql數(shù)據(jù)庫名 ? $conn=mysql_connect($mysql_server_name $mysql_username $mysql_password $mysql_database);? ? $sql= CREATE?DATABASE?mycounter?

PHP連接數(shù)據(jù)庫之PHP連接ACCESS數(shù)據(jù)庫代碼方法

? ? $conn?=?new?("ADODB Connection");? ? $connstr?=?"DRIVER={Microsoft?Access?Driver?(* mdb)};?DBQ=" ?realpath("data/db mdb");? ? $conn Open($connstr);? ? $rs?=?new?("ADODB RecordSet");? ? $rs Open("select?*?from?szd_t" $conn );? ? while(!?$rs eof)?{? ? $f?=?$rs Fields( );? ? echo?$f value;? ? $rs MoveNext();? ? }? ? ?

PHP連接數(shù)據(jù)庫之PHP連接MS SQL數(shù)據(jù)庫代碼方法

安裝SQL服務(wù)器并添加PHP的MSSQL擴(kuò)展

使用以下代碼連接并測試

?php? ? $myServer?=?localhost;?//主機(jī) ? $myUser?=?sa;?//用戶名 ? $myPass?=?password;?//密碼 ? $myDB?=?Northwind;?//MSSQL庫名 ? $s?=?@mssql_connect($myServer ?$myUser ?$myPass)? ? or?die(Couldnt?connect?to?SQL?Server?on?$myServer);? ? $d?=?@mssql_select_db($myDB ?$s)? ? or?die(Couldnt?open?database?$myDB);? ? $query?=?SELECT?TitleOfCourtesy+?+FirstName+?+LastName?AS?Employee?;? ? $query? =?FROM?Employees?;? ? $query? =?WHERECountry=USA?AND?Left(HomePhone ? )?=?( );? ? $result?=?mssql_query($query);? ? $numRows?=?mssql_num_rows($result);? ? echo? h ? ?$numRows? ?Row? ?($numRows?==? ???:?s)? ?Returned?/ h ;? ? while($row?=?mssql_fetch_array($result))? ? {? ? echo? li? ?$row[Employee]? ? /li;? ? }? ? ?

PHP連接數(shù)據(jù)庫之PHP連接Oracle數(shù)據(jù)庫

PHP提供了兩套函數(shù)與Oracle連接 分別是ORA_和OCI函數(shù) 其中ORA_函數(shù)略顯陳舊 OCI函數(shù)更新?lián)f更好一些 兩者的使用語法幾乎相差無幾 你的PHP安裝選項應(yīng)該可以支持兩者的使用

　?? if?($conn=Ora_Logon("user@TNSNAME" "password"))? ? {?echo?"SUCCESS?!?Connected?to?databasen";? ? }else? ? {echo?"Failed?: (?Could?not?connect?to?databasen";}? ? Ora_Logoff($conn);? ? phpinfo();? ? ?? ? lishixinzhi/Article/program/PHP/201405/30761

如何實現(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;

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！";
