PHP连接MYSQL数据库代码

PHP连接MYSQL数据库代码
--------------------------------------------------------------------------------
<?php
$mysql_server_name='localhost'; //改成自己的mysql数据库服务器
$mysql_username='root'; //改成自己的mysql数据库用户名
$mysql_password='12345678'; //改成自己的mysql数据库密码
$mysql_database='mycounter'; //改成自己的mysql数据库名
$conn=mysql_connect($mysql_server_name,$mysql_username,$mysql_password,$mysql_da tabase);
$sql='CREATE DATABASE mycounter DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci; ';
mysql_query($sql);
$sql='CREATE TABLE `counter` (`id` INT(255) UNSIGNED NOT NULL AUTO_INCREMENT ,`count` INT(255) UNSIGNED NOT NULL DEFAULT 0,PRIMARY KEY ( `id` ) ) TYPE = innodb;';
mysql_select_db($mysql_database,$conn);
$result=mysql_query($sql);
//echo $sql;
mysql_close($conn);
echo "Hello!数据库mycounter已经成功建立！";
?>
PHP连接MS SQL数据库代码方法
--------------------------------------------------------------------------------
1.安装SQL服务器并添加PHP的MSSQL扩展
2.使用以下代码连接并测试
<?php
$myServer = localhost; //主机
$myUser = sa; //用户名
$myPass = password; //密码
$myDB = Northwind; //MSSQL库名
$s = @mssql_connect($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 .= WHERE Country=USA AND Left(HomePhone, 5) = (206);
$result = mssql_query($query);
$numRows = mssql_num_rows($result);
echo <h1> . $numRows . Row . ($numRows == 1 ? : s) . Returned </h1>;
while($row = mssql_fetch_array($result))
{
echo <li> . $row[Employee] . </li>;
}
?>
-------------------------------------------------------------------------------- 通过PHP连接MYSQL数据库
$conn = mysql_connect("localhost","root","password") or die("无法连接数据库");
mysql_select_db("table" ,$conn) or die ("找不到数据源");
通过PHP创建MYSQL数据库
$conn = mysql_connect("localhost","root","password") or die("无法连接数据库");
mysql_create_db("webjx") or die("无法创建数据库");
$sqlstr = "create database other_webjx";
mysql_query($sqlstr) or die("无法创建,一般请检查权限什么的");
创建mysql的表
$conn = mysql_connect("localhost","root","password") or die("无法连接数据库");
mysql_select_db("webjx",$conn) or die("无法连接数据库webjx");
$sql = "create table webjx_table(
ids integer not null auto_increment ,
primary key(ids)
)";
$mysql_query($sql) or die(mysql_error());
